The 4000 grit Resin Bond Diamond Matrix stone was formerly known as one of our "polishing stones" .

After experimenting with the resin bonded diamond stones in lower grits, we decided that we were going in introduce them as a whole new line of stones in a league of their own.

If you're wanting a polished edge, and you find the polishing tapes to be too delicate, this is definitely the solution for you.

The diamond Matrix line was designed for the sharpening fanatics that insist on the best. Attention to detail and quality are immediately visible when you hold them in your hand. The 4000 grit Matrix sharpening stones have a special feel of their own, and last an incredibly long time.

As the resin bonded diamond stone wears, new diamond particles are exposed so the stone continues to cut at the same rate not losing any performance.
