Handheld Diamond Sharpening Stones


Style A	Style B	Style C

Style D	Style E	Style F

Style G	Style H	Style J

Style K

Hold these stones with one hand to sharpen your blade at any angle. Our hardest and longest-lasting abrasive, diamond quickly sharpens blades of any material. Use these stones dry or with water. Rinse with water to clean.

Full Dimple Coverage


Style A	Style B

Shallow dimples collect debris to prevent clogging the sharpening surface. These stones are a good choice for blade edges with defects that require heavy material removal. They also reduce friction and heat to protect delicate blades while you sharpen.

Styles A and B—Fold the sharpening end into the handle for compact storage.

Without Dimples


Style C	Style D	Style E

Style F	Style G	Style H

Style J	Style K

The dimple-free surface sharpens blades evenly every time. Since these stones have the most abrasive, they also remove material more quickly. However, debris can build up rapidly, so you’ll need to wipe them clean more often.

Styles C, J, and K—Fold the sharpening end into the handle for compact storage.

Diamond Sharpening Compounds

Convert leather and wood surfaces into sharpening stations to give your tool a fine finish. These compounds contain diamond abrasive grains, which are hard, fast cutting, and long lasting. They're used on leather strops and other flat surfaces to sharpen straight blades. To sharpen curved blades, you can also use these compounds on curved surfaces.

Pastes

Start with pastes for sharpening—sequence them by grit to refine the edge progressively.

Diamond Sharpening Compound Assortments

Keep multiple abrasive grain sizes on hand to sharpen blades. Convert leather and wood surfaces into sharpening stations to give your tool a fine finish. These compounds contain diamond abrasive grains, which are hard, fast cutting, and long lasting. They're used on leather strops and other flat surfaces to sharpen straight blades. To sharpen curved blades, you can also use these compounds on curved surfaces. Start with the largest abrasive grain size, then move to smaller sizes to sharpen your blade to a progressively finer edge.
