Sharpening Stones

Quickly sharpen straight-blade tools.

Rectangular Stone

Single Grit

Two Grit

Three Grit

Two Grit—A different grit on each side enables two-step sharpening with one stone. First sharpen your blade with a lower grit, then sharpen again with a finer (higher) grit until the desired edge is achieved.

Three Grit—Three separate grit surfaces enables multistep sharpening with one stone. First sharpen your blade with a lower grit, then sharpen again with progressively finer (higher) grits until the desired edge is achieved.

Aluminum Oxide—Aluminum oxide cuts more slowly than silicon carbide for finer control. Also known as India stones.

Novaculite—Novaculite has extremely fine grains that cut very slowly for the most control over sharpening. Also known as Arkansas stones.

Silicon Carbide Abrasive—Silicon carbide cuts quickly with light pressure. Also known as Crystolon stones.

Aluminum Oxide Ceramic Abrasive—Aluminum oxide ceramic is extremely hard and wear resistant.

Lubrication Required—For stones that require lubrication, we recommend using a water-soluble or oil-based lubricant.
