SJ-250 Japanese Waterstone


The SJ-250 Japanese Waterstone is 4000 grit and provides a mirror finish. The fine surface of the grindstone polishes the edge and creates the ultimate surface finish. If you want razor sharpness, this is the grinding wheel for you! Fits the Tormek T-8 and all earlier machine models with a grinding wheel 250 mm (9 7/8″) in diameter.

Tormek also recommend cleaning the stone surface of steel particles every minute or so using the fine side of the SP-650 Stone Grader. Do not use the coarse side of the Stone Grader on the Japanese Waterstone.

  • Provides superior sharpness.
  • Fits the Tormek T-8, Tormek T-7 and older models

Mirror Finish – Never in Vain

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.
