Work Sharp is the sharpening brand from Darex, a family-owned manufacturer based in Ashland, Oregon, that has been building precision grinding equipment since 1973. Their sharpening systems use flexible abrasive belts, guided rod platforms, and diamond plates depending on the product line—each designed around a different use case and skill level.
The Ken Onion Edition is Work Sharp's flagship powered sharpener, developed in collaboration with custom knifemaker Ken Onion. It uses variable-speed flexible belts and an adjustable guide to sharpen at angles from 15 to 30 degrees, handling everything from kitchen knives to axes and garden tools. The belt system conforms to curved and serrated edges that fixed-angle stones can't reach, which makes it effective on gut hooks, recurves, and hawkbills in addition to standard blade profiles.
The Precision Adjust series takes a manual, guided-rod approach for users who want full control over angle and pressure. These systems clamp the blade in place and use interchangeable abrasive plates—coarse diamond, fine diamond, and ceramic—to work through a progression from reprofiling to polishing. The guided platform removes the guesswork from freehand sharpening while keeping the process entirely manual.
Work Sharp's field sharpeners are compact, portable units designed for use at the campsite, cleaning station, or in the shop. They combine diamond plates, ceramic rods, and leather strops in a single tool for quick edge maintenance between full sharpenings.
