The newly designed dual-sided combination whetstone from Fallkniven features a super fine white ceramic stone (0, 1 micron) with a grit of 1400 to 2000 and the dark grey ceramic stone is made of synthetic sapphires (1 micron) and has a grit of 800-1000. There is no need to add any oil or water, just lay the blade on the stone, raise the blade's spine and deburr your blade on the grey side until it has a razor-sharp edge and then use the smooth white side to get a nice polished edge.
Frequently, our recommendation for beginning sharpeners is to start with diamond stones as their strengths make them ideal to build a sharpening toolkit around. Diamond stones are low maintenance and durable, lasting many years with only occasional cleaning. They are among the fastest stones to use making them time efficient. Diamond grit will handle even very hard steels, and diamond stones can be used for flattening waterstones. All these things make diamond stones a practical foundation for your sharpening toolkit.
The Work Sharp WSKTS-KO performs double duty as a knife sharpener and a tool sharpener. Its ability to perform multiple tasks is part of why this sharpener looks so intimidating. Instead of using spinning discs like most electric sharpeners, this Work Sharp uses belts. In fact, it works a lot like a typical electric sander. A motor pulls the belts along so that they gently shave away at whatever you place them against.
Now hold the handle of the knife firmly in one hand and, with the blade facing you, place it on the sharpening stone at an angle of 10 – 20 degrees. Make sure that there is a gap less than a 1/4 inch between the back of the blade and the sharpening stone. Place your free hand on the blade, but never directly on the cutting edge. We are pretty serious about this one. Touching the cutting edge can lead to some serious injuries so please be careful.
The blades of Sugimoto Hamono Japanese knives are tempered using the traditional mizu-yaki process which gives the metal a harder finish compared with Western knives. As a result, if you sharpen the cutting blade so that it becomes too thin, it will not be able to maintain its mechanical strength and may chip. In addition, you need to use a flat-surface whetstone to back-grind a Japanese knife. Be careful not to over-grind the blade. Blades made using the hon-kasumi method consist of two different layers of metal that are forge-welded together. Since the blade is composed of two layers, it may slightly bend over time, but this can be corrected at our Company. Single-beveled-blade knives cut with the back side of their blade. Please take particular care that this back side does not become rusty.
Honing is kind of like dusting the furniture while sharpening is more like reupholstering the furniture. Honing is purely a maintenance activity that should be regularly practiced to make sure the blade is clean and sharp as can be every time you use it. It’s easily done using a honing rod, a leather strop or a sharpening stone; as most stones have a side for sharpening and a side for honing. Honing is akin to trimming your hair to remove the split ends. It’s not a full on haircut. What it does is realign the tiny sharp protrusions along the edge of the blade that can be bent over with use, so that they stand more or less straight.
Vielsalm Coticule on the other hand generally occurs in much more narrow layers sandwiched between the slate layer and the Belgian Blue layer and thus, it is both less plentiful and more expensive than Belgian Blue stone. Also, Coticule is divided into different grades and sometimes displays blemishes on the surface due to its proximity to the slate layer. Furthermore, it is somewhat harder than Belgium Blue stone and, due to its brittleness, it is bonded to a substrate layer of hard slate prior to sale to prevent the stone from breaking during use.
TO USE: Soak stone in water for no more than 5-10 minutes. Place stone on a damp cloth with the courser 400 grit side (dark green) facing up. Hold the knife so that it’s flat and perpendicular to the block, with the blade facing left. Holding the knife at a 20-degree angle, slowly sweep the edge of the blade from left to right down the length of the stone and continue until sharp. If stone starts to feel too dry, add more water. Be patient and take your time. Flip knife over and repeat on the other side (now moving from right to left). Be sure to sharpen both sides evenly. To polish the blade further, flip stone over to the fine 1000 grit side (light green) and repeat the process. When blade is honed to desired sharpness, wash and dry your knife. To clean your stone, simply rinse with water, wipe away any remaining metal residue with a rag, rinse again, then dry.
