A: People often make the mistake of assuming that just because a mechanical knife sharpener will sharpen the edge of a knife that means it will sharpen any type of cutting edge, including scissors. This is a mistake and can wind up being a costly mistake when you have to replace both your scissors and the knife sharpener. There are sharpening devices specifically designed to handle scissors. Or you can bring your scissors to a sharpening pro who will usually have the right equipment on hand to also sharpen scissors. Another thing to keep in mind about trying to use a sharpener to sharpen scissors is that by using the device in this fashion you are likely voiding the warranty. As such if you damage the device trying to sharpen scissors you’ll need to pay to have it repaired or replaced as the warranty won’t cover it. Also, certain types of high end scissors also come with a warranty. And, just as with the sharpener itself, if you try to sharpen them using a mechanical sharpener you can say goodbye to the warranty protection. The bottom line is to always use the appropriate tool for the job at hand. That way you’re assured of the best possible result and any warranty remains in effect.
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 Sunrise Pro doesn’t have the pedigree of some other knife sharpeners on our list but it performs as advertised and that’s all that matters. For a relative song you get to restore all the knives, steak knives, cleavers in your kitchen to near pristine condition. It’s easy to use and the nice strong suction cup on the bottom means you can put the band aids away.
I love this whetstone pendant!! I’ve been wearing it a couple weeks now and this thing not only performs like a champ but looks really cool. I originally left a 3 Star review like a jerk because I didn’t like the fact that my stone was all white. Idve rathered some markings but after wearing and using this thing the markings are something I could really care less about. This piece is super functional, extremely well crafted and looks great as an edc sharpening stone/necklace!! You guys rock!!
A sharpening stone is a stone that has got a coarse side and usually a finer side, and that is going to take and re-shape your edge and get it back down thin enough in order to sharpen it. You are basically taking something that is blunt and thinning it back down. You have to remove all of this extra metal and get it back down to where it is thin enough to cut. Very simply, all a knife is is a very thin piece of steel to split whatever you are cutting. If the knife is obviously thicker, it is like trying to cut something with a chisel; it is not going to happen.
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.
For woodworking tools like chisels and plane blades, you will need stones that are at least as wide as the blades themselves. Length is helpful but not always critically important. The one exception is when you're using a guide for sharpening tools. The guide often rides on the stone and longer stones permit you to use a much larger portion of the stone as both the guide and the edge need to simultaneously touch the stones.
The composition of the stone affects the sharpness of the blade (a finer grain, usually, though not always, produces sharper blades), as does the composition of the blade (some metals take and keep an edge better than others). For example, Western kitchen knives are usually made of softer steel and take an edge angle of 20–22°, while East Asian kitchen knives are traditionally of harder steel and take an edge angle of 15–18°. The Western-style kitchen knives are generally in the range of 52–58 on the Rockwell scale, which denotes the relative hardness of a material.
In recent years, some whetstone manufacturers have started producing ceramic whetstones made from hard, ceramic, powders that are mixed with Aluminum Oxide and then sintered to form a solid. But, rather than using oil or water to lubricate the whetstone, ceramic whetstones are meant to be used without lubrication and thus, they provide a significant advantage for chefs who need to keep their knives sharp but, who do not have either the room or time for using a bench water stone. Thus, they are commonly available as either bench stones, pocket stones, round rods, or triangular rods.
It helps you get the knack for a consistently correct angle BUT the idea falls apart a bit when it comes to the curve and taper part of the knife and if your knife has an excessively narrow (slicer/boner) or wide (cleaver) width. It will also mark up the sides of your knife which may bother some who are obsessed with the cosmetic appearance of their $150+ Japanese knives--I could care less.
I love sharing information, please never hesitate to comment if you are stuck or need some advice on water stones. Speaking of that, if you have more than one stone, start with the coarse and end with the fine stones and repeat the process on each stone. However, you only need P4 pressure on that first stone, the the Raising of the Burr Pressure. After that, keep it moderate to light.
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.
Over the course of two days I re-sharpened nearly a dozen old blades, including removing the secondary bevel on an old stainless Ontario saber-grind Navy diver's knife, convexing the edge on flat ground 1095 Schrade 55 that also came with a secondary bevel, and fixing a broken tip on an old Kershaw folder. These stones made quick work of the Schrade and Kershaw. Both had completely new edge geometry within 30 minutes apiece. The Kershaw looked like-new, as if the tip had never broken. And the Schrade cut much better than it's secondary bevel would previously allow, regardless of how sharp I got it with a ceramic rod and strops. The Ontario took a little more work, as it had been abused a little the last time I'd held it, over 25 years ago and was as dull as a case knife - one of the reasons I decided to go ahead and do a full saber grind - well, a slightly convexed saber, I suppose would be more accurate. But within under an hour of using the two stones and a couple leather strops (one with black compound, another with green), the Ontario was shaving sharp again too.
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.
Begin with your lower-grit stone. Place the heel of your knife on the far edge of the stone, holding the blade gently but firmly with both hands at a 15- to 20-degree angle. Using even pressure, slowly drag the knife over the stone toward you down the length of the stone while simultaneously moving the knife such that the contact point moves toward the tip of the blade.
I am just starting out sharpening with whet stones. I have found these stones to be very nice and the instructional videos that come along with the set on knifeplanet are extremely helpful to anyone starting out. The cost of the set was very reasonable and seems to be a great value. The customer service is amazing, I lost the site for the videos and sent an email to get the information and immediately there was a reply with all of the links that I needed. I appreciate their attention to their customers!!
