Tormek SJ-250 Japanese Waterstone

Tormek Japanese water whetstone SJ-250

For a mirror-like surface and razor-sharp results.

The SJ-250 Japanese Waterstone is designed for sharpening hand tools such as woodcarving tools, knives, scissors, plane irons and chisels, which require minimal steel removal and superior sharpness. It's perfect for both sharpening nerds who want to be able to see their own reflection in their bevels and meticulous craftspeople who want really clean cuts.

It's designed to give the tool the finest surface finish, so its abrasive power is limited and it can't be used to shape a tool. If you need to give your tool a new edge, it's best to do that on another grinding wheel first and then use your SJ-250 Japanese Waterstone to give the final finish.

The unique composition of the stone gives it an extremely long service life. You usually don't need to hone on the leather honing wheel afterwards because the SJ-250 Japanese Waterstone leaves such a fine finish.
