The Specs

Diamond Efficiency, Slim Profile

Diamond abrasive removes metal faster than ceramic or Alundum - making this stick effective for both restoring a dull edge and maintaining a sharp one. The double-sided design gives you coarse and fine in a single tool. The slim profile stores easily in a knife roll, drawer, or on a magnetic strip alongside your knives.

Care and Maintenance

• Wipe clean with a damp cloth after use
• Allow to dry fully before storing
• Suitable for double-edged knives - use with care on single-bevel blades
• Replace when diamond surface shows significant wear
