Resin Diamond Sharpening Stones

Professional-Grade Resin Diamond Sharpening Stones

Achieve razor-sharp edges with the same technology trusted by professional knife sharpeners. Our Resin Diamond Sharpening Stones combine industrial-grade diamond abrasives bonded in a durable resin matrix — delivering faster cutting, longer life, and a consistently flat surface that traditional whetstones can't match.

Available in 6 grits to cover every stage of sharpening:

• 120 grit — Heavy stock removal, reprofiling damaged or very dull edges
• 320 grit — Coarse sharpening, establishing a new bevel
• 600 grit — Medium sharpening, refining the edge
• 1000 grit — Fine sharpening for everyday maintenance
• 3000 grit — Pre-polish finishing
• 5000 grit — High-polish, razor-sharp final edge

Why Resin Diamond?

Diamond abrasives cut faster and more aggressively than ceramic or natural stones, while the resin bond cushions the cut for a smoother feel and finer finish. The result is a stone that stays flat longer, requires no soaking, and works on all steel types — including hard stainless, high-carbon, and tool steels.

Perfect for:

• Home cooks who want professional results
• Professional knife sharpeners and culinary pros
• Chefs, butchers, and outdoor enthusiasts
• Sharpening knives, chisels, plane irons, and other edged tools

Whether you're restoring a neglected blade or maintaining a razor edge, Grind's Resin Diamond Sharpening Stones give you the precision and control to get the job done right.
