“It's a free stone so can't complain. Two grits and a handy size. If I had the choice I would have liked a case of some description to keep it safe but as a freebie it's excellent.”
“This came free with a knife. Easily puts a very sharp edge on the knife. Quite small & so probably only good for smaller blade knives (maybe up to 3" blade) . On the plus side the small size means could slip in a back pack if on your travels.”
