Japanese Whetstone-Synthetic Stone

Synthetic whetstones are the everyday tools of Japanese knife sharpening: consistent, reliable and available in every grit. Coarse stones (#120 to #400) repair chips, medium stones (#800 to #1200) do most of the work, and fine stones (#3000 and up) refine and polish the edge.

If you only buy one, make it a #1000. Our grit guide explains what to buy next.
