Norton-Saint Gobain Abrasives JM3 Coarse Grit Crystolon Benchstone As Replacement Part For IM313 Oilstone System, Silicon Carbide, 11-1/2" x 2-1/2" x 1/2"

Excellent quality stone. I find it is a better water wet stone

Combine this tri stone set with a Japanese whetstone and you will have no issues after years. First stones lasted 3 years, and we are replacing them, basically, because a lot of people uses it inside our professional kitchen, but not everyone is careful enough.

A decent coarse grit block, it seems to be wearing somewhat quickly however---does a good job reshaping the bevels on a blade.

works as it should

really good

Love it thank you
