A shinkansen is a Japanese-style pull-through sharpener named after the famous bullet train. It features two sets of ceramic wheels set at the right angle for sharpening a Japanese blade, which takes out the guesswork of the waterstone. Simply hold the handle with your left hand, then saw back and forth gently through the coarser wheel to sharpen, before switching to the finer wheel to polish.
We get asked regularly to recommend stones for the beginning sharpener. Everyone wants to get stones that will be of the most practical use. No one wants to waste money on something they will have to replace later. The goal is to get stones that can be used as a foundation for your future needs. But the number of options available can be bewildering to the inexperienced sharpener, leaving many wondering where to start.
The stone – With a sharpening stone, the process is essentially the same as with the stick sharpener. The only difference is that you don’t hold the stone, you place it into its own holder (If it comes with one. If it doesn’t you’ll need to improvise) on a flat surface. Push the knife down the stone several times while holding it at a shallow angle and then flip it and pull it toward you several times to get the other side of the blade.
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.
It will be tempting to raise the angle here to get to the edge quickly, that is not the way to go. Re-paint the edge/bevel if necessary and try again. You can flip the knife prior to burr formation and work on the opposite side. Repeatedly feel for the burr with your thumb by running it very gently down the blade and over the edge, if the burr is there it will be very obvious, you need to create the burr along the entire length of the blade. Once you have done that, (you have accomplished what most people will never try) but besides that, you have to do the same to the other side of the blade.
When the stone is intended for use on a flat surface, it is called a Bench Stone. On the other hand, small, portable, hand-held stones are referred to as Pocket Stones. Also, because Pocket Stones are smaller than Bench Stones, they are more easily transported but, they also present difficulty in maintaining a consistent angle and even pressure when attempting to sharpen longer blades. Consequently, Bench Stones are commonly used at home or in camp whereas, Pocket Stones are generally reserved for honing an edge in the field.
Aesthetics – While it’s true that most people keep their sharpener, (even their expensive mechanical sharpeners) in the drawer until it’s time to use them you’ll still want to be aware of whether your sharpener fits into the overall aesthetic of your kitchen when you do take it out to use. While sharpener designs are fairly limited to be sure you typically have some control over the color and finish of the device as well as design factors like whether the device is boxy or rounded in appearance. With a stone sharpener or a stick however you pretty much get what you get.
For the common sharpening purpose, generally, people tend to use two phases. In the first phases, they use the coarse stone to shape the edges then jump to the finer stone. In application, these of the two phases can be extended with the grit stone in between. It might be varying in the number of grits or mesh in different types of sharpening stone.
Select the grit of the stone. Sharpening stones are available with different grit sizes. For example, you can choose fine, medium and coarse stones. You should use a coarse stone followed by a fine grit if your knives are dull. If your knives have been sharpened recently or they aren't too dull, consider using a medium grit. Try to use a grit level ranging from 325 (for coarse) to 1200 (for extra fine).
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.
Table mounted device – Typically the manual powered table mounted sharpener looks virtually identical to the electric powered sharpener with a slot for each stage. Where they differ is that each slot in the manual powered sharpener has only one groove and you pull the blade through this groove toward you to sharpen the blade. Once the blade is sufficiently sharp you place it in the honing groove to refine the edge and pull it toward you again several times. If there is a third, cleaning, stage you repeat the process for that stage as well.
Historically, there are three broad grades of Japanese sharpening stones: the ara-to, or "rough stone", the naka-to or "middle/medium stone" and the shiage-to or "finishing stone". There is a fourth type of stone, the nagura, which is not used directly. Rather, it is used to form a cutting slurry on the shiage-to, which is often too hard to create the necessary slurry. Converting these names to absolute grit size is difficult as the classes are broad and natural stones have no inherent "grit number". As an indication, ara-to is probably (using a non-Japanese system of grading grit size) 500–1000 grit. The naka-to is probably 3000–5000 grit and the shiage-to is likely 7000–10000 grit. Current synthetic grit values range from extremely coarse, such as 120 grit, through extremely fine, such as 30,000 grit (less than half a micrometer abrasive particle size).
Now to finish: Again with P1 pressure, trailing strokes only, this time lift the blade off the stone as you finish pushing it over the stone away from you, bring it back and repeat this 5 times, on each side. The burr should be gone and your knife will be sharp, remember, manage your expectations but if you have followed this, that knife is going to be sharper than when you started and this is just the beginning. Now you can test your knife for sharpness trying to cut some telephone book paper.
My Fujiwara is an exceptional cutter and a pure joy to use, as a result, the mediocre knives get a pretty good break and the dream knife gets to do the lions share of food preparation. So it gets duller faster. However, it goes without saying that superior steel will have improved edge retention but at the end of the day, knives get dull, they just do and I am very happy about that, I get to sharpen them over and over!
After you have completed a few passes over the stone on both sides, you can move to the final stage. This time it is P1 pressure, just enough pressure for you to control the knife. Ensure your stone is wet and now repeat the motions but with very very light pressure. You really need to focus here and ensure you are reaching the edge of the edge and again, just a few sweeps on both sides of the knife.

Understanding Grit: You’ll see a bunch of numbers being thrown around when discussing the grit of a sharpening stone. The number refers to the size of the grit. The larger the number, the finer the grit. A good beginner stone would be a two-sided stone with #400 and #1000 grit. The #400 grit is the courser stone for working out the nicks and imperfections, the #1000 grit is for refining.
Whetstones may be natural or artificial stones. Artificial stones usually come in the form of a bonded abrasive composed of a ceramic such as silicon carbide (carborundum) or of aluminium oxide (corundum). Bonded abrasives provide a faster cutting action than natural stones. They are commonly available as a double-sided block with a coarse grit on one side and a fine grit on the other enabling one stone to satisfy the basic requirements of sharpening. Some shapes are designed for specific purposes such as sharpening scythes, drills or serrations.
The whetstone is the most popular for sharpening pocket knives (or knives). But, before you go into the sharpening, you must prepare the whetstone beforehand. Don't worry, it's quite easy. The majority used can be done by dipping the stone in water for about 15 minutes. Regardless of what type of whetstone you use, never use it while it's dry. It's important for a clean sharpening. Using mineral oil is another way to prepare a whetstone. It'll absorb into it once you begin putting the right amount on the surface. How you will determine how much to put is to ensure a "thick film" is lathered across the entire surface. This is critical when you learn how to sharpen a pocket knife.
The word “Novaculite” is derived from the Latin word “novacula”, which means “razor stone” and is essentially a metamorphic, recrystallized, variety of Chert composed mostly of microcrystalline quartz that is found in the found in the Ouachita Mountains of Arkansas and Oklahoma and in the Marathon Uplift of Deposited in the Devonian Period and the early Mississippian Subperiod some 410 to 325 million years ago and subjected to uplift and folding during the Ouachita orogeny of the Atokan Epoch (early Pennsylvanian Subperiod), Novaculite is a very tough stone that is resistant to erosion and thus, the various layers of Novaculite stand out as ridges in the Ouachita Mountains. Thus, due to both its availability and its composition, it has been mined since ancient times for use as arrowheads and spear heads as well as in more modern times for use as sharpening stones.
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.
A: We’re all told that a sharp knife is safer than a dull knife yet most everyone knows that merely touching a sharp knife can often result in a painful cut while we can wrap our hand around a dull blade with little worry. So why would anyone in their right mind claim that a sharp one is safer than a dull one? To a certain extent it’s a matter of semantics for sure, because there is no denying you have to be extremely careful around really sharp knives. But at the same time there is a very good reason to consider a dull knife to be more of a safety hazard than a sharp knife.
A: When it comes to the best knife sharpeners used in a domestic setting the abrasives used to sharpen the blade should last for quite a few years. When they do eventually wear out many of the best manufacturers will refurbish them for you, typically for a nominal fee. Again, however, unless you are using the sharpener on a daily basis (and there is virtually no reason the average person would do this), the sharpener should last for many years before ever needing service.
The following are my personal favourites and they are all synthetic stones, I do have experience with natural what stones but lets keep it simple, lets stick to synthetic water stones. Believe me, some of the world sharpest knives are sharpened solely on synthetic stones. Here are my personal favourites, I use these water stones every day and the order is not necessarily in priority, they are all good.
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.
Pressure is something that is sometimes not mentioned but in my experience and in my opinion, it is extremely important to apply the correct amount of pressure, I use three different levels of sharpening pressure, with my sharpening pressure being measured on a scale from 1-5 with 1 being very light and 5 being maximum pressure. When you initiate the sharpening process, when you have all your ducks lined up and you are ready to start, use P4 (Pressure at level 4, almost maximum). in this case it is you and the stone working together, you are going to apply pressure with your finger tips (2 or 3 finger tips) placed as close to the primary edge as you can get, i.e. over the area you are working on, on the opposite side of the blade. As you push the knife away from you in a trailing motion, apply P4 pressure to the knife as it glides over the wet whetstone, (whet means sharpen) you will see the black residue start to form in the water on the surface, this is Swarf and this is good, don’t feel obliged to remove this with water, it is fine. Continue working from the heel to the tip of the knife moving your fingers along the edge and applying pressure as you move the knife away from you on the right side of the knife and as you pull it towards you on the left side, these are called edge trailing strokes.
Just to prove that we're not merely sharpening geeks, here's an interesting side note. The word whet pops up in some unexpected places. A small species of owl is called the saw-whet owl because the sound it makes reminded people of the sound made when sharpening a saw with a file. And the phrase "to whet your appetite" comes from the idea of your hunger growing sharper at the thought of food.
A single stone of 120 grit and a combination stone of 1000 and 3000 grits come along with a stone holder all for a price of less than many other individual stones. The stones are 6 7/8" long and 2 1/8" wide. A flattening stone of some kind would be needed, but with economical options available in those, the overall price of this kit would still be low. This entry level set is a good budget minded option.
Our large selection of stones from many well-known manufacturers will allow connoisseurs to find the ideal stone for their needs. Because all manufacturers formulate their stones to emphasize a different mix of qualities, and because these qualities can vary widely between different stones, most woodworkers choose stones from several manufacturers to build up an optimal set of sharpening stones. Then again, once you get to know the characteristics of certain types of stone, you may find one supplier who will provide all the stones you need. Sometimes this can be an advantage. But there is no one size that fits all; each stone must fit your needs and work style.
Selecting the proper coarseness for your sharpening stone is an important first step in sharpening your knife. Not every knife needs to start at the coarsest stone you have, on the other hand a very dull knife can not be sharpened on only your finest stone. Starting with the proper coarseness will ensure that you achieve the edge you need quickly. If your knife is very dull or has a nicked blade, start with your coarsest stone. The coarse stone removes material quickly so a poor edge can be refined quickly. However, the coarse stone must be followed up with your finer stone to refine the edge. If your knife is only slightly dull and just needs a quick touch up, starting at a medium or fine stone can save you time. Starting on a fine stone requires fewer steps but must only be used on an edge requiring little work.
The final Chef’s Choice sharpener on our list is the 316 Diamond Sharpener. Like the 15XV the 316 is at its best when used to sharpen Asian-style knives and it does so with unflinching effectiveness and speed. This is a compact, 2-stage electric sharpener that produces the 15 degree edge so favored in Asian cutlery. Ideal for the preparation of sashimi or sushi.
Made from hand-selected A36 hot rolled steel that is left untreated to allow it to age naturally and beautifully from season to season, Stahl's new X firepit will be a center of warmth and attention for generations. Each minimalist firepit is made in Portland, Oregon and includes four 3/16 inch steel pieces that can be assembled in minutes with no complicated parts or screws.
This is a good size stone and has the two different grits needed for knife sharpening. No instructions were included, but there are many websites with written and video instructions, so this is not an issue for most people. A fair amount of dust is generated during the sharpening process, so protect the work surface and wash the knife after sharpening is completed.
A great sharpener for all your kitchen knives the CS2 also makes a smart addition to the gear when you’re going away on a family camping trip. It will also do a bang-up job on your hunting, pocket, boning knife and more. As mentioned it does require just a bit of getting used to in order to achieve optimal results but nothing too involved. A simple, effective, no-frills sharpener.
The Whetstone 2-Sided Sharpening Stone is made from professional grade corundum and will sharpen everything from a razor blade to a cleaver and even a machete, should you happen to have a machete lying about that needs sharpening. This is the simplest type of sharpener it’s true but the company have obviously put a great deal of thought into the product.
The coarse stone will cut the metal off quicker but it is going to give you a rougher edge but that way the job gets done quicker, without the oil. It is not as messy. This is just a real simple set up. If you do wood work you can make a little wooden box and rout it out. In this particular case it is just a 2x4, stone traced out, finishing nails tapped down so they are deeper than the stone so when you drop the stone in, if you are at a workbench you can C-clamp it down in place or you can hold on to it.
