Smith's 3-in-1 Sharpening System

This product is no longer available, but don't go just yet.


  • Fine 750-grit diamond stone provides a quick razor-sharp edge
  • Stone features multiple layers of micron-sized monocrystalline diamonds securely bonded to a flat metal surface
  • Pre-aligned carbides provide quick edge-setting capabilities with just three or four strokes; use on very dull knives or to restore a damaged edge
  • Carbide heads are reversible and replaceable: when heads stop cutting they can be rotated and used on the other side
  • Multi-use fine ceramic rods provide a smooth razor sharp edge; designed to sharpen straight and serrated edged knives
  • Rods fit securely into specially shaped slots in bottom of base for safe and easy storage
  • Hook groove in diamond stone and rods will sharpen all size hooks
  • Storage lid protects the diamond stone and also serves as a hand guard during sharpening
  • Non-slip rubber feet keep base from shifting while sharpening
