I thought I had the best stones using PDTools until I tried the hybrid series from KDTU and then realized I was wrong. The scratch pattern is magical and these stones require zero effort to cut and refine. You just pick an angle and keep it even and you end up with some of the best looking bevels I've seen.

These stones really surprised me; they cut amazingly well and left my blade with a mirror finish. I’m going to buy the whole collection—thanks, Hapstone.
