Available in three sizes 1x6" and 2x6" mounted on aluminum backing for the EdgePro (for use where space and portability is a concern) and 3x8" mounted on glass to give an exceptionally flat surface with outstanding characteristics. Use the 3x8" size in standard stoneholders One of the smoothest leathers available. These selected kangaroo leathers are from thinner hides and provide extreme flatness because there is less compression giving remarkable edges.

This leather provides minimal abrasion itself but still has the draw of leather. Use this as a final finish after using your finest natural or synthetic stones or diamond lapping surfaces. Use it on your razors and knives for the sharpest and finest finish available on this planet! Great for edge touchups.
