Use this Medium-Grit Whetstone To Sharpen Steel Knives, Including Chroma Type 301 Kitchen Knives

Chroma Type 301 kitchen knives are made of exceptional steel – Japanese 301 steel - and most feature blades honed to the “V” shape edge traditionally found on Japanese knives. This makes Chroma knives sharper than conventional kitchen knives. But still, like all knives, these will lose their sharp edge over time and require re-sharpening. Be sure to use a high-quality whetstone. For the absolute best results, Chroma recommends pre-sharpening using a rough-grain stone, then a medium-grain stone and finally, a stone of very fine grain to achieve a polished finish. However, this medium-grit stone is considered quite appropriate for regular care and maintenance.

Use the Chroma 800-Grit Whetstone with Care!

Protect your investment. Before you attempt to sharpen any knives using your Chroma whetstone, take time to learn the proper technique. You'll begin by soaking the whetstone in water for about 15 minutes, and you'll need to keep it damp throughout the sharpening process. We recommend you view this helpful video. Among other things, it will provide instruction on how to determine whether your knife blade is truly dull and how to hold the knife (at an angle of 15 to 20 degrees).
