KDTU Hybrid CBN (Thin)

Looks like it's very well made. A quality product. It is exactly the same thickness as the Hapstone starter stones so no need to readjust anything when using successive stones. Stone is very coarse at 50 grit but it's still smooth. First 50 grit stone I've ever bought. I was nervous that it would be too rough, but it isn't. Stone cuts rapidly and is great for starting on a really dull knife, or fixing a chip or a broken tip.
