The 4-sided diamond hone block has a different grit on each face, ranging from extra coarse (200 grit) to fine (600 grit). Each surface of the knife sharpener has three layers of diamonds that are nickel bonded to the steel frame. The hone block fits into a non-slip ABS mount. Use water in a spray bottle instead of oil to coat the diamond sharpening surface.
