Dear Mr. Carmona: From the first time I spoke to you by telephone, I have been greatly impressed by your willingness, even your eagerness to take your time from your own personal activities to assist me. I am awed by your extensive knowledge and work in a field that is such a benefit to so many people in so many kind of activities. Your website is a real asset, and a testimony to your desire to be helpful. I wish to thank you again for your kindness as well as your fervor in the way your company deals with interested parties, even those who may purchase nothing, or only small items, as I have done.
Whetstone has two different sides of grain for sharpening and polishing knife edges. These softer Japanese stones have several advantages over harder stones. Because they are softer, they do not become glazed or loaded with detritus. Plus, they are lubricated effectively with water rather than oil, but can be used with either. Submerge the stone in water for about 5 - 10 minutes. Continue to apply water while sharpening with the Whetstone Cutlery Two sided Whetstone Sharpening Stone. The stone releases small particles during the sharpening process; this powder in combination with water allows the sharpening. After a while you will notice a small burr at the edge. Now repeat the same process on the other side of the blade. Finally, turn the stone over and repeat the procedure, this time using the finer grit of the stone. In order to remove the remaining burr, pull the blade at an angle over the stone. Rinse the stone and clean off the grinding residue. Clean your knife with hot water.
If you do not remove enough metal to create a new edge, you will leave some of the dull edge in place. A dull blade (or a blade with dull spots or nicks) will reflect light from the very edge of the blade. A razor sharp knife edge will not show "bright spots" when you hold it blade up under a bright light. You will need to remove enough material from the sides of the bevel so that the edge stops reflecting light.
We're not completely sure but we think we now have the largest selection of sharpening stones on the face of the earth. If you're interested in something and don't see it here please contact us and we'll try to get it. Most of the stones you see here are Japanese water stones, both synthetic and naturals. There is also a wide selection of stone holders, flatteners, and other items that will help you get a razor sharp edge on all your sharp tools and knives. 

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.
2. Although I’ve been sharpening knives for a while, I never could get a knife sharp using the freehand method, I’ve had to rely on various jigs to set & maintain a constant angle to the bevel. To begin with, the Lanksy knife sharpener kit was my main tool, but then I found a South African jig made by Warthog Knife Sharpeners. I still have their first model, which, if memory serves me, came out in the late 1990’s. This has since been upgraded & is supplied with a diamond stone, which is worthless unless it’s going to be used for ceramic knives. However-the Warthog & the Warthog Multi-Blade’s modus operandi has the knife moving ABOVE the stone, unlike the Lanksy / Edge Pro / Edge Pro Chinese copies & variants. ( No oil / water dripping off the stone from above the knife). Also, the Warthogs use any bench-size whetstone available to its owner, a very big plus if you want to use your grand-dad’s old Arkansas stone.No tie in having to buy the manufacturer’s specialised stones which work only with one type of sharpening jig.
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. 

When a whetstone is used to cut metal, it acts like sandpaper by removing small particles of metal (aka “swarf”) with each pass of the blade over the stone. Therefore, whetstones with more coarse grits cut faster than those with finer grits and, at the same time, soft whetstones cut faster than hard whetstones because each pass of the blade over both types of whetstones not only removes fine particles of metal from the blade, it also removes fine particles from the surface of the whetstone (aka “slurry”) which continuously exposes new cutting crystals. However, if the swarf is allowed to build up on the surface of the whetstone during sharpening, it will clog the stone and drastically diminish its effectiveness. Therefore, some whetstones require water to lubricate the stone and suspend the swarf whereas, other whetstones require oil to lubricate the stone and suspend the swarf.
You’ll know you’re reached a stopping point when you can feel the slight catch of the bevel on the edge of the blade, by carefully running your finger in the direction of the blade, or by cutting through a sheet of paper. When the knife cuts cleanly through the paper, it’s time to hone the blade. Read our guide for more information about honing vs sharpening.
In summary: Peter Nowlan is a professional knife sharpener based in Halifax (Canada) and he recommends the KnifePlanet Sharpening Stone Set, a beginners and intermediate kit that includes 4 sharpening grits: 400/1000, 3000/8000, a bamboo base and the KnifePlanet Flattening Stone. The Japanese Naniwa 3-stone combination is also a great (and more expensive) choice, ideal for professionals and more advanced sharpeners: the Naniwa stones are slightly bigger compared to KnifePlanet’s. In both cases, a coarse, medium and fine grit combination is very effective to sharpen and refine the edge:
We’ve shown you how to keep knives sharp before, and even discussed why water stones are best, but this crash course is quick, fast, and gets to the point. In most cases the most the average person at home can do is either hone their blade with a honing steel, which straightens and lines up the blade’s edge, but it doesn’t sharpen it. Alternatively you could run it through a handheld or electronic sharpener, but depending on the model you use it can do more harm than good.
