Furi Ozitech Diamond Fingers Knife Sharpener. This revolutionary design incorporates eight stainless steel spring fingers bonded with crushed industrial diamonds, inside a tough folding clam-shell case which doubles as a handle and hand guard when unfolded. Hones to an ideal 20 degree angle on both sides of the blade. Creates professional edges, with no skill required - just three swipes (pulling the knife down and back) through the fingers ensures razor sharp edges.
