For instance, American Novaculite (aka Washita and Arkansas Stones) is a form of metamorphic Chert that produces some of the best known and best loved natural whetstones in existence. Then, there is a form of Belgian Coticule which has been known for providing extra-keen edges since Roman times and, there is a Japanese Siliciclastic sedimentary stone (aka Japanese Water Stones) which consist of a fine silicate particles suspended in a clay matrix. Plus, there are also various types of man-made whetstones available such as Silicon Carbide (aka Crystalon) stones and Aluminum Oxide (aka India Stones) as well as a synthetic Corundum (aka Ruby) rod and Aluminum Oxide impregnated ceramic rods as well as several different types of diamond hones.
With 100 percent diamond abrasives and proprietary Trizor Edge technology, this knife sharpener has been engineered to give your knives an incredibly sharp and professional edge. Although it’s designed to professional standards, it’s easy for anyone to use, with magnetic guides that properly position the knife in the sharpening slots and help increase control of the sharpening process.
Not sure why I bought this item and then I received it. It has a bit of a 'cool' factor and is well made. I took the sharp edges of the stone as they were a bit uncomfortable on my chest but have since been wearing it a lot. Used it to put an edge on some workmates knives and to tickle up my own daily use knife. I like it, it is a bit different and useful.
Here is the most important part. Even if you don’t believe what I have said here you will believe this: Gadgets rob you of one of critical components of knife sharpening. With them, there is no connection between you and the knife, there is no sense of pride, no accomplishment. I was able to make knives sharp years ago, what propels me these days, what drives me to improve is the emotional feedback given to me by the entire sharpening process, this is not possible with a gadget and using one is like putting a piece of bread in the toaster. (not a good toaster either). Sharpening knives has a multitude of personal rewards attached to it, these are what you should strive for and hang on to. These are not part of the gadget world.

One of the main advantages of choosing this stone sharpener over others, is the ease of use, efficiency and consistency. It might take a while before you can properly sharpen with a wet stone. However, the Chosera 1,000, makes the whole process easy and fast. There are no complicated processes. All you have to do is push and pull your blade across the surface and you are good to go. You obtain a razor-sharp edge. In short, everyone can do it.
Many popular American and European kitchen knives have roughly 20-degree bevels on both sides of the blade. Some traditional Asian knives, however, have a different edge design, with a bevel on just one side of the blade, or bevels of a narrower angle, closer to 15 degrees than 20. A knowledgeable retailer should be able to explain the edge geometry of your knife and how to tailor the sharpening process to accommodate it.
Some models can sharpen serrated knives but the economic models usually will not so be sure you check the manufacturers' documentation. Generally, you can touch up your serrated knives with great success by using to last or finest stage of an electric sharpener. To really sharpen each serration then you normally need around tapered sharpening rod, or you need a manual sharpening kit (like the Gatco 10005 or 10006).
Keep your knives in top shape with our wide selection of handheld and countertop knife sharpeners. The best way to make your knives last longer is to sharpen them more often, and now you can do so quickly and conveniently in your own kitchen. Dual-stage slots help you get the perfect edge that you’re looking for, and the rubber grips make daily use easy and safe. A good knife sharpener refines the edge and bevels at just the right angle for your knives each and every time. Choose from our automatic or manual sharpeners to suit your needs. We also offer steel rods and sharpening stones for more traditional methods of knife-sharpening. Our professional-grade sharpeners are worth the extra care they can provide for your knives, and the three-stage and extra fine sharpeners will serve your ultra-sharp knives for filleting fish or fine-slicing best. You can also rely on the rubber feet on the bottom to prevent your sharpener from skidding or sliding on your countertop. Sharpen blades up to 10.5 inches in length down to knives that are under six inches. Do not use conventional sharpeners for blades with a serrated edge. After you’ve finished sharpening, check the edge’s quality by cutting into a sheet of paper.
Most sharpening stones are made of aluminum oxide, Novaculite, and silicon carbide. They are commonly known as India, Arkansas and Crystolon stones. Crystolon and India are man made while Arkansas stones are natural. Arkansas stones have a fine to coarse texture while India stones are preferred for fine sharpening. Crystolon are mainly used for initial coarse sharpening. Some sharpening stones are mixed with diamond abrasives to produce the optimal cutting edge.
I'm a novice knife sharpener. I've had to unlearn what my grandpa taught me in order to use these. So far, I've had decent but mixed results. I've switched to my cheap 200/400-ish cheap tool stone from harbor freight for cutting a bevel when the blade has either been damaged or did not have a proper bevel. The 400/1000 grit stone in this kit is soft. Very soft. I have bowled it out several times. It makes keeping a steady angle difficult. But these stones at this price point are meant for learning, and for that they serve their purpose.

The Fallkniven DC3 Diamond/Ceramic Whetstone Sharpener will make a believer out of anyone willing to invest a bit of time in the process. A big advantage of this stone is that it can be taken anywhere, used anywhere, without any form of lubrication and will produce an amazing sharp edge on whatever needs sharpening. Timeless Old World tech that still dazzles.
Newer knife sharpeners have been designed with you in mind. They are quick and easy to use. They figure out the angle for you, so you can focus on learning skills in other areas of your life without wasting time learning how to hold a knife. This page has been designed to bring you the best of the best of today’s most popular kitchen knife sharpeners. Of course, some of the older style sharpeners have prevailed in popularity over the years and we will be sure to include a couple of those here as well.
Why spend hundreds of dollars on a knife sharpening machine when you can get your knives razor sharp for the price of a cheap necktie? It won’t take more than a few practice sessions to learn how to get your knives professionally sharp with the Lansky 8” Ceramic Sharp Stick. This device is simplicity incarnate and yet it does the job of electric sharpeners costing many times more.
Various Angles – If you want to ensure that you’ll be able to achieve the exact edge that you’re after, you’ll want to make sure to choose a manual knife sharpener that is equipped with an angle adjuster. Typically, this will appear as a knob and you’ll be able to turn it to adjust the degree of the angle. Choosing one of these devices, with a wide range of angles, is a very smart choice. The Smith’s Adjustable Manual Knife Sharpener is a good buy here.
The edge the Trizor XV made was the best in our tests. In contrast to the “toothy” edge that the manual Chef’sChoice ProntoPro 4643 creates, the Trizor XV polishes an edge to a razorlike finish—meaning the knife is perfectly capable of straight-up-and-down chop-cutting of items like onions and garlic, as well as traditional push- and pull-cutting. Perhaps the highest compliment we can give the Trizor XV is that, when the test was done, we resharpened the knives that we had used with the rejected competition models on the Trizor XV.

Modern synthetic stones are generally of equal quality to natural stones, and are often considered superior in sharpening performance due to consistency of particle size and control over the properties of the stones. For example, the proportional content of abrasive particles as opposed to base or "binder" materials can be controlled to make the stone cut faster or slower, as desired.[7] Natural stones are often prized for their natural beauty as stones and their rarity, adding value as collectors' items. Furthermore, each natural stone is different, and there are rare natural stones that contain abrasive particles in grit sizes finer than are currently available in artificial stones.[citation needed]
DICTUM is about more than just tools - For more than 160 years, DICTUM has been offering an extensive range of tools, including garden tools, materials, finishes as well as knives for the kitchen and for outdoor use that meet the highest standards and requirements. In our opinion, first-class tools are defined by haptics, ergonomics, material and manufacturing quality. That is how inspiring, durable tools are made.
Stones are divided into hard oilstones (often called Arkansas stones), which use mineral oil or kerosene as a lubricant, and soft (often called Japanese) waterstones, which use water as a lubricant. Whereas the hard oilstones rely on directly abrading the knife steel, the soft waterstones wear away rapidly as you sharpen, producing an abrasive slurry that cuts the new edge; they work more quickly, but you have to regularly reflatten them by rubbing them against a sheet of glass. With both kinds, you have to set and maintain the sharpening angle using only your eyes and hands, and any sloppiness can quickly produce a rounded edge that will hardly cut butter. Doing it right is not all that hard once you get the knack, but there’s a difficult initial learning curve. You also need at least two stones, coarse and fine, to do a proper job—and good stones aren’t cheap. And both oilstones and waterstones make a bit of a mess in use and take a lot more time to set a new edge than the sharpening tools we recommend here—10 to 20 minutes versus three minutes or less.
Stone is awesome, stand and rubber holder are awesome. Sharpened my Benchmade griptilian with a 154CM (58-61HRC) stainless steel blade to easily shaving hair in about 10 minutes or less, on the 4000 side. Can probably get it sharper, too. Completely worth the money, and very easy to use after a few minutes of reading - don't waste any money on pre-built sharpeners - they suck.
This is one of those shave off a lot of metal and end up with a wedge edge knife sharpeners. IF you never sharpen your knives and you can use them backward and not notice then this is a good deal. It will take a heck of a lot of metal off the blade and the edge is not great but it's a lot better than what you had, and it didn't take long. And in a few years when the blade is so bull it can work as a potato masher do it again. But if you have a "good" knife, not necessarily a $$$ knife, then this won't make you happy. It will leave you with a rough and pretty wedgy, but sharp, edge. Use this regularly and your blade will be a toothpick because of the amount of metal removed.
I recently placed my first order after finding you on the web while looking for grinding wheels. I am a customer for life. Here's why. My first order was a simple white grinding wheel for a "normal joe's shop". When I received the wrong wheel (150 grit instead of the ordered 100 grit) I called and without hesitation or the 3rd degree another wheel was sent off. No questioning of my integrity, intelligence or honor. Simply "I am sorry, we'll send the correct wheel off immediately..." The right thing was done by a neat guy. I was treated like an adult. Unbelievable in this day and age...proper...and priceless. Price, performance, responsiveness and customer service par excel-lance. 6-Stars! All my sharpening orders, albeit small shop orders, will now be with you. Promote you I will.
When starting out sharpening, it won’t be long before you hear about the “toothy” vs “polished” edge. It will suffice to know that a 1k stone is going to give you an edge that will perform beautifully as will a knife finished at 5k. There is a belief that a knife that has a highly polished finish, 5k and up will be so polished that it’s toothy goodness will be erased. This knife will not bite into the skin of a tomato for example because the edge is too polished, it will slide over the top. This is not always true, if the knife has been sharpened well, i.e. if Side A and Side B of the blade meet precisely at the Apex of the knife, that edge will slide into a tomato quite beautifully. I have seen many brand new Japanese knives with highly polished 8k edges that no tomato skin can stand up to.
In order to formulate a better opinion about each of these, you will want to read the information below. Each unique knife user will prefer one specific knife sharpener to the others. Over time, you will do the same. Until then, it is best to read the information below and allow it to guide you to the best knife sharpener for your individualized needs.

Lastly, the stropping stage. Remember seeing old barber shops on television? Remember that leather paddle they used to buff the straight razor? That is stropping. The strop can be leather or canvas and it's the final step in polishing the blade, making an even surface. Depending on the use of the knife, this step may be omitted. A chef will not require the blade precision chopping vegetables that a barber requires shaving with a straight razor on a gentleman's face. The chef may simple steel the blade and keep working.
Unfortunately, this sharpener is not meant for use with serrated blades, unlike some of the others on this list. Also unfortunate is the fact that I was unable to find any record of the angle degree to which it will sharpen a blade. However, consumers have been very happy with its performance and estimate the angle to be somewhere around 16 to 18 degrees.
These are very popular stones. 8" Dia-Sharps have a single grit per stone making them more expensive, but at 8" by 3" they are wider than the 8" DuoSharps, offering a good working surface. The 8" Dia-Sharp line also has the widest range of grits available from DMT, with extra extra coarse, medium extra fine and extra extra fine options not available in other sizes, so it is good line to consider. One coarse and one fine stone is a good starting point.
Be aware that few sharpeners of any type can properly sharpen serrated knives; that’s a job best left to a professional, so we didn’t knock points off our test models if they lacked the capability. Luckily, serrated knives tend to stay sharp for years and years, since it’s the teeth (rather than the edge) that do most of the work. For this review we focused on the sort of knives that sharpeners are designed for: those with standard, straight-edged blades, such as paring and chef’s knives.
For the kitchen, you will want to equip yourself with a durable, convenient and lightweight knife sharpener. If the product is too difficult and time consuming to use, it will not function sufficiently for serious chefs. The KitchenIQ 50009 is excellent for this specific purpose. Although it is slightly small, it will get the job done quickly! The price makes this a suitable product for almost everyone, regardless of skill level.
“Great knife-edge maintainer!!! This is the best sharpener I’ve used for keeping a keen edge on your best kitchen knives. It’s primarily for the last step in maintaining a keen edge on the knives you use every day. It’s not for neglected knives that need a significant amount of metal removed. This would be great for maintaining a new set of quality cutlery. If you are looking for perfection to keep your best knives in top shape, this is the unit to get … I find that half to one dozen strokes every so often will keep your knives as sharp as the day you got them.”

In contrast to the “toothy” edge that the manual Chef’sChoice ProntoPro 4643 creates, the Trizor XV polishes an edge to a razorlike finish—meaning the knife is perfectly capable of straight-up-and-down chop-cutting of items like onions and garlic, as well as traditional push- and pull-cutting.

Grinding is generally done with some type of sharpening stone. Sharpening stones come in coarse and fine grits and can be described as hard or soft based on whether the grit comes free of the stone with use. Many sources of naturally occurring stones exist around the world; some types known to the ancient world are no longer used, due to exhaustion of former resources or the ready availability of superior alternatives. Arkansas, USA is one source for honing stones, which are traditionally used with water or honing oil. India is another traditional source for stones. Ceramic hones are also common, especially for fine grit size. Japanese water stones (both artificial and natural) come in very fine grits. Before use, they are soaked in water, then flushed with water occasionally to expose new stone material to the knife blade. The mixture of water and abraded stone and knife material is known as slurry, which can assist with the polishing of the knife edge and help sharpen the blade. Generally, these are more costly than oilstones. Coated hones, which have an abrasive, sometimes diamonds, on a base of plastic or metal, are also available.

This three stone package is a good place to look if a larger surface area in oilstones is what you’re after. The 11 1/2" long by 2 1/2" wide Coarse Crystolon, Medium India and Soft Arkansas stones provide more work surface than the smaller oil stones giving flexibility to sharpen knives and many other tools as well. The plastic housing retains the oil, keeping the stones bathed and ready to go.
Budo's sharpening stone is an excellent buy. The 1000 and 4000 grit stone is a good mix for sharpening everyday household knives. The alignment tool also helps a person hold a knife at the proper angle so that they don't inadvertently flatten the edge and dull the blade. The stone has a rubber seat so that it doesn't slide within its bamboo stand. The only negatives are that detailed instructions are not included with the packaging, however, a link is sent to your e-mail address but that doesn't help if it's a gift. Also the tool doesn't work well with short knives like a paring knife. Lastly, the 1000/4000 stone isn't quite suitable for professional level knifeware but Budo does sell higher grit sharpening stones.
A sharp knife is a safe knife. If it's used to cut food, even sporadically, after some time, the blade will dull. This will then cause you to need unnecessary pressure and force to cut foods the blade used to glide right through. Although you can prolong your blade's sharpness by refraining from using it on glass or marble surfaces and cleaning and storing properly, it will require extra care at some point. Learn about the ways in which you can keep your cuts crisp, slices thin and your cutlery in tip top shape.
The leather strops are the real trick to getting the knife scalpel sharp with the much sought after mirror edge. The leather for whatever reason just makes a sharp knife crazy sharp. All the knives I process to a .5 micron mirror finish can all whittle hair. I recommend that everyone get at least the 14 / 10 micron strops as the leather really helps refine any edge.
I enjoy these stones so much that the feedback is not a deterrent at all for me, I don’t even think about it. The results are always nothing but top notch, they deliver exactly what I want, some of the sharpest knives I have ever produced were sharpened on Shapton Glass stones. They may be thinner but they last a very long time, they are easy to maintain as well,
The Chef's Choice 1520 AngleSelect knife sharpener's three sharpening stages can do just about anything. It has a dedicated slot for sharpening 20-degree Western knives, a second slot for sharpening 15-degree Asian knives, and a third slot with a flexible polishing/stropping disk to help polish off a smooth, sharp edge. Spring-loaded blade guides keep everything at just the right angle. This Chef's Choice sharpener is also pretty quiet for an electric model, and very safe.

Works better than a diamond sharpening stone for knives.Non-slip bamboo holder keeps everything secure so you never have to worry about the Japanese whetstone slipping off the counter.Whetstone knife sharpener makes all your blades last longer - use the coarse 3000 grit to prep and smoothen the blade then finish honing and polishing with the 8000 side.Slice through anything with ease and achieve the real precision of a pro when you have a truly razor-sharp knife, chisel, or axe.Made from White Corundum, so expensive oil .
By employing separate sharpening slots, the ProntoPro 4643 is capable of sharpening both older European-style knives (such as from Wüsthof and Henckels) and Japanese-style knives (such as from Mac—which makes our favorite chef’s knife—and Shun). The difference is in the angle of the bevel that forms the cutting edge: Traditional European knives have roughly 20-degree bevels, while Japanese knives have roughly 15-degree ones. If you own both types of knife, or if you do a lot of heavy work in the kitchen (like chopping up chicken carcasses), you’ll appreciate this feature, as a 20-degree bevel is best for tough jobs. Note, though, that Wüsthof and Henckels have stopped making 20-degree knives, having switched to 15-degree or 12-degree designs exclusively in 2011; the reason is that for all but the heaviest tasks, these more-acute bevels cut better and, with the ongoing improvements in steel alloys, hold their edges for just as long.
As discussed in The Sweethome's review of the Professional Knife Sharpener from Brod & Taylor, some pull-through knife sharpeners that make use of a V-notch sharpening system tend to remove too much metal from the knife. However, The Brod & Taylor machine's design overcomes this problem by precisely guiding the knife blade to create a perfect angle. This sharpener features a tungsten carbide sharpening system.
To use a whetstone you run the knife's blade back and forth across the stone's surface and due to the constant friction with the stone, which acts like a piece of sandpaper, the knife's edge becomes razor sharp and has a brilliant mirror shine. If you are a beginner at using a whetstone it can a take a while to master the sharpening process, so here is a video to help you with your sharpening stone skills.
In terms of other random stuff I utilize, I use the masking tape to prevent the vise from scratching the blade as detailed above. The alcohol and Gibbs Oil are used to clean the blades as often they are covered in gunk and other random crap. The sharpie is to apply to the edge of the knife to make sure the entire bevel is being sharpened. Eventually once you have used the system long enough it will not be needed as you will know what to look and feel for.
A blade's sharpness may be tested by checking if it "bites"—begins to cut by being drawn across an object without pressure. Specialized sticks exist to check bite, though one can also use a soft ballpoint pen, such as the common white Bic Stic. A thumbnail may be used[3] at the risk of a cut, or the edge of a sheet of paper. For kitchen knives, various vegetables may be used to check bite, notably carrots, tomatoes, or cucumbers. In testing in this way, any nicks are felt as obstacles.
Jigs, such as the industry-standard Edge Pro, are an extension of the stone method, as they use simple but cleverly designed armatures to maintain a consistent angle between the stone and the blade. They’re extremely effective—professional knife sharpeners are some of their biggest champions—but they’re also expensive, and really practical only with a dedicated workbench.
The Chef’sChoice ProntoPro 4643 is our overall pick among knife sharpeners. A manual model, it was the easiest of all our test models to use—almost intuitive, in fact: You insert the blade in one of the slots and run it back and forth, from heel to tip, until the tool grinds a new edge. The sharpening elements are wheels impregnated with diamond abrasive—a material that Cook’s Illustrated found to be superior (subscription required) to ceramics in both sharpening speed and lack of friction. In our test, about 30 strokes on the coarse wheels under light pressure cut a brand-new edge. Another 20 strokes on the fine, polishing wheels gave the edge a reasonably smooth finish.
“Great knife-edge maintainer!!! This is the best sharpener I’ve used for keeping a keen edge on your best kitchen knives. It’s primarily for the last step in maintaining a keen edge on the knives you use every day. It’s not for neglected knives that need a significant amount of metal removed. This would be great for maintaining a new set of quality cutlery. If you are looking for perfection to keep your best knives in top shape, this is the unit to get … I find that half to one dozen strokes every so often will keep your knives as sharp as the day you got them.”
Its main disadvantage is cost: At about $120, the flagship stainless steel Professional model sits in an uncomfortable middle ground between our main pick and our upgrade pick. That said, an otherwise identical Classic model made of black plastic is generally closer to the price of our main pick. A lesser point, but an important one, is that this design is not completely foolproof, as our other picks are. You have to pay attention and use a steady hand and pressure to get a straight edge. Not hard—but you may need a little practice to master the process.

This is a great sharpener for budget conscious cooks. You can use it with equal facility whether you’re right or left handed, it has a convenient finger guard to cut down on accidents and most important, it only takes a few swipes on a regular basis to keep your knives in tip-top condition. It’s not glamorous. It won’t add anything substantive to your kitchen decor. But it will ensure your knives are always ready for whatever dish you have in mind.

Beginning on the right side of the knife, move from tip to heel and heel to tip, then flip the knife and repeat. For the left side, it’s opposite—start at the top of the stone to reach the heel area completely. So, you will move from heel to tip and then tip to heel. Remember to apply and release pressure as you did earlier, exactly the same as in Step 2, but with light, refining pressure.

Out of the box, the sharpener looks well built with top-notch fit and finish. It is quite boxy in appearance, with a pronounced slot running down the middle. Inside the slot sits multiple diamond-infused ceramic wheels that interlock and rotate counterclockwise in relation to each other in order to sharpen both sides of the edge simultaneously. The unit runs smoothly with minimal noise.

Aluminum-Oxide oil stones are very popular man-made sharpening stones produced by an abrasives company called Norton and which are commonly called India Stones. Generally less expensive than Arkansas stones (aka Novaculite), these stones are graded coarse, medium, and fine and are designed for fast cutting. Yet, when the fine grit is used, they can also produce a relatively fine edge. Also, because India Oil Stones are both softer and coarser than Arkansas Stones, they are commonly used in conjunction with Novaculite to cut the initial edge bevels or, repair extremely dull or damaged edges before refining and polishing the bevel with an Arkansas Stone.


This is a good quality stone for a beginner looking to learn about hand sharpening knives and blades. It holds up well, especially for the price point. New sharpeners are prone to gouging and scratching stones, pushing too hard, etc, and this stone handles the abuse nicely. The no slip base is very effective at cementing the stone in place, which is a critical safety feature.
Stropping a knife is a finishing step. This is often done with a leather strap, either clean or impregnated with abrasive compounds (e.g. chromium(III) oxide or diamond), but can be done on paper, cardstock, cloth, or even bare skin in a pinch. It removes little or no metal material, but produces a very sharp edge by either straightening or very slightly reshaping the edge. Stropping may bring a somewhat sharp blade to "like new" condition.
At age 10, Terada learned the basics of sushi from his father and then went on to attend RKC Chef's School in Kochi, Japan from 1987-1989. He soon earned a nickname for his fast knife, attention to detail, divine presentation and ability to create new dishes and accents based on traditional Japanese cuisine. After graduating RKC Chef School, he was called to serve under Master Chef Kondo at Yuzuan restaurant in Kochi, Japan from 1989-1992. Mr. Kondo is the master of Kansai style cooking, considered to be the high-end of Japanese cuisine. Terada earned the title Master Sushi Chef by becoming the standing head sushi chef & can serve Fugu (Japan Licensed) to the public.
The kind of tech we love: compact, reliable, durable, attractive and cheap. Purists may feel that other sharpeners will produce a more perfect result but for 99% of the human race this sharpener will be everything the doctor ordered. Your blades stay sharp for a good long time thanks to the 2-stage sharpening process and if you’re a left handed chef you’ll love the fact that it works just as effectively for you as for anyone else.
You've likely seen someone using a honing rod to "sharpen" a knife. But the steel rod doesn't actually sharpen your knife—it just straightens out the cutting edge on the blade to allow for smoother, safer cuts. Sharpening your knife, on the other hand, actually, well, sharpens it. So yes, you need to do both. Hone your knife weekly—every time you use your knife, if you'd like—and sharpen your knife every few months, or at least every year (depending on how often you use it, and how soon you notice dulling that honing doesn't really improve).
As for the drawbacks, there’s almost nothing bad about the Chef’s Choice 15 Trizor XV at all. It’s a solid candidate for the award of the best electric knife sharpener out there. Of course, if you’re nitpicky you may find the sharpener’s dimensions of 10 by 4.25 by 4.25 inches a bit larger than the norm. But that shouldn’t be a problem even if you have limited space in your kitchen. Besides, it looks good in either brushed metal or platinum finish.
To summarize, Shapton Glass 500, 1,000 and 2,000 is a good combination and if you would like to throw in the 4,000 grit stone in lieu of the 2,000 that is good as well. If your knives are very hard, ZDP 189 for example, this is a fantastic choice. (They are also excellent for tools, chisels etc. and they are the premier choice for many Straight Razor honers).
Clamp-style sharpening tools use a clamp with several holes with predefined angles. The stone is mounted on a rod and is pulled through these holes, so that the angle remains consistent. Another system is the crock stick setup, where two sticks are put into a plastic or wooden base to form a V shape. When the knife is pulled up the V, the angle is held so long as the blade is held perpendicular to the base. Several cutlery manufacturers now offer electric knife sharpeners with multiple stages with at least one grinding stage. These electric sharpeners are typically used in the kitchen but have the ability to sharpen blades such as pocket or tactical knives. The main benefit of using an electric sharpener is speed with many models that can complete the sharpening process in one to two minutes. The disadvantage is that the sharpening angle is fixed so some specialized knives, like a Japanese style Santoku, may need additional attention to sharpen to the ideal angle.
