The DMT WM8FC-WB DuoSharp 8″ Fine/Coarse is a WM8FC-WB DuoSharp 8-inch double-sided diamond whetstone, Fine (600) on one side, Coarse (325) on the other, with non-slip base. Plated and finished at DMT’s Marlborough, Massachusetts plant — DMT’s monocrystalline diamond particles are aggressive enough to flatten waterstones, and the larger DuoSharp / Dia-Sharp formats stay flat indefinitely.
Right sharpening stone for woodworkers, chefs, hunters, and anyone tired of dished waterstones or worn-out oil stones. DMT is the default reference for American-made diamond sharpening.
