Lansky Double-Sided Diamond Benchstone Coarse/Fine

A double-sided diamond benchstone with a red coarse side to repair and recondition damaged or dull blades, and a blue fine 600 grit side to produce and maintain a working edge. The uninterrupted diamond coating runs edge to edge. The 15 x 5 cm stone sits in a non-slip, self-storing base with screw holes for bench mounting.
