Boride Aluminum Oxide Dressing Stone is a maintenance stone for cleaning, refreshing, flattening, and resurfacing sharpening stones in 6" x 1" Edge Pro form factor. It uses White Aluminum Oxide abrasive with Boride vitrified bonds F9 and G9.

It provides controlled resurfacing and routine maintenance with lower risk of excessively roughening the stone surface. Compared to Silicon Carbide versions, it works more gently and leaves a smoother refreshed surface.

Boride classifies F9 as “Soft” and G9 as “Medium”, though practical differences between the two bonds are relatively small in knife sharpening applications.

Available grits: F150, F220, F320.
