I got this today. I can't for the life of me remember who has the collection of these sorts of hones but this one is 6.5"x2 1/4" x a hair over 3/4" and it still retains its original slurry stone.This one is interesting in the sense that it is not in a paddle and it has the defined form factor/slurry stone. Haven't had a chance to give it a shakedown yet. Harder than a thuringian to lap. Slurry looks like if you mixed chinese mustard with water.
