Diamond Paste for Knife Sharpening:

Discover how solid diamond paste with increased concentration can turn your dull knives into razor-sharp precision tools.

What Is Diamond Paste and Why Does It Matter for Knives?

Diamond paste is a high-performance abrasive compound made with micro-sized synthetic or natural diamonds suspended in a paste base. It’s used by knife sharpeners, chefs, craftsmen, and hobbyists to achieve a mirror-like edge and superior cutting performance.

For knives, especially high-carbon steel or stainless steel blades, diamond paste offers unmatched sharpness, consistency, and control compared to traditional sharpening compounds.

What Makes Increased Concentration Solid Diamond Paste So Effective?

Solid diamond paste with increased concentration contains a higher percentage of diamond particles, which makes it more aggressive and precise. Its dense consistency allows better contact with the blade and reduces waste during application. This type of paste is ideal for:

  • Restoring dull knives
  • Fine polishing and mirror-finishing
  • Achieving razor-sharp, long-lasting edges

Unlike liquid pastes, the solid version stays in place on leather strops or belts, offering better control during manual or mechanical sharpening.

Choosing the Right Diamond Grit for Your Knife

Diamond paste is available in various grain sizes (grits), each serving a specific step in the sharpening process:

  • Coarse Grit (63/50, 40/28, 28/20)
    Best for reshaping damaged or extremely dull edges. Quickly removes steel and resets the bevel.
  • Medium Grit (20/14, 14/10, 10/7)
    Used for refining the edge after coarse sharpening. It smooths out micro-chips and prepares the blade for fine polishing.
  • Fine Grit (7/5, 5/3, 3/2)
    Ideal for finishing the edge. Produces a sharp, clean, and refined cutting edge for kitchen and utility knives.
  • Ultra-Fine Grit (2/1, 1/0)
    Used for final polishing and creating a mirror finish. Essential for professionals who demand maximum sharpness and aesthetics.

How to Apply Diamond Paste on a Leather Strop

  • Apply a small amount of solid diamond paste evenly on a clean leather strop using a plastic spatula or soft cloth.
  • Start with coarse grit to shape the edge, then gradually move to finer grits for refinement and polishing.
  • Stroke the knife edge along the strop at a consistent angle, maintaining steady pressure.
  • Repeat several times on each side of the blade for best results.

Who Is It For?

  • Professional knife sharpeners looking for high-performance abrasives
  • Chefs and kitchen enthusiasts maintaining razor-sharp culinary tools
  • Outdoor and EDC users who rely on dependable blades
  • Knife makers and restorers polishing custom or vintage knives
