Fallkniven Whetstones

Sharpen anywhere, sharpen everything.

The Fallkniven DC3 and DC4 whetstones are compact, high-performance sharpeners combining two ultra-durable materials: a fine diamond stone (25 micron) and a ceramic stone made from synthetic sapphire. This powerful duo can sharpen even the hardest modern steel—including high-end powder steels—with no need for oil or water.

Whether you're out in the field or maintaining your gear at home, these pocket-sized sharpening stones deliver professional-level results in a simple, portable format.

Two Surfaces. One Perfect Edge.

Diamond Side (25 Micron)

Ideal for restoring dull or damaged edges, the industrial diamond surface cuts quickly and can handle even the hardest steels.

Ceramic Side (Synthetic Sapphire)

Use the ceramic surface to refine your edge to a razor finish. Synthetic sapphire ensures long-term flatness and consistent results over time.
