Lansky Tri-Stone Benchstone

A three-stone bench sharpener combining diamond, alumina-oxide and ceramic surfaces on one base. The coarse diamond stone re-profiles very dull or damaged blades, the medium alumina-oxide stone handles most touch-ups, and the fine ceramic stone polishes to a smooth, shaving edge. Each surface measures 51 x 152 mm (2 x 6"), and the wide plastic base has non-slip rubber feet and screw holes for bench mounting.
