Our take on the DMT Machining A-PROKIT Dia-Sharp Whetstone Sharpening Kit

The DMT A-PROKIT is a three-piece diamond whetstone kit: coarse, fine and extra-fine Dia-Sharp stones plus a holder with a guide rod. Diamond abrasive cuts fast on hard steels, including high-vanadium and powdered-metal blades that wear conventional waterstones. It suits cooks and outdoors users who want a compact, low-maintenance sharpening set. Against waterstone kits it needs no soaking and stays flat, but it leaves a coarser finish and gives less feedback than natural stones.

What grits are included?

Three Dia-Sharp stones and a stone holder with a guide rod.
