Sharpening Stones & Whetstones

Peakkit's sharpening stones and whetstones subcategory covers the full range of bench stones and diamond plates used in freehand knife sharpening. From coarse-grit reprofiling stones to ultra-fine finishing stones, we stock the brands and grits that serious sharpeners use.

Diamond sharpening stones

DMT and Lansky diamond plates cut faster than conventional abrasives and maintain their flatness longer. Available in coarse (200-325 grit), fine (600 grit) and extra-fine (1200 grit) options. Diamond stones work on all steel types including hard steels that defeat conventional abrasives.

Waterstones and combination stones

Japanese water stones and combination oil stones with contrasting grits on each face are popular entry points into freehand sharpening. Grit progression from 400-1000 through to 3000-8000 produces a polished working edge on most kitchen and outdoor knives.

Ceramic and natural stones

Spyderco benchstones, ceramic finishing rods and Arkansas natural stones sit at the fine end of the abrasive spectrum. They're used for final-stage polishing and touch-up work rather than reprofiling. Browse our guided systems and rods subcategory for angle-controlled sharpening options.
