Boride Silicon Carbide Hard Dressing Stone is a maintenance stone for cleaning, refreshing, flattening, and resurfacing sharpening stones in 6" x 1" Edge Pro form factor. It uses Black Silicon Carbide abrasive with Boride K10 vitrified bond.

It provides aggressive resurfacing with higher structural stability and more controlled abrasive release. Compared to D10, it releases abrasive more slowly and works primarily through its hard textured surface.

Temporary glazing may occur during use but is rapidly refreshed during dressing.

Boride classifies K10 as “Medium”, though its practical behavior in sharpening applications is noticeably harder than D10.

Available grits: F150.
