Overview
A kitchen drawer holding Santoku and other Asian-style knives gains this handheld sharpener, which pulls blades through diamond abrasive wheels. Crisscross sharpening and a precise bevel guide produce a fine edge with real bite.
Diamond wheels work in both directions at once, and the finishing step adds polish. Wheels hold their shape, unlike ceramic ones that wear. The fixed narrow angle limits which knives it suits.
Who it's for
People with Santoku and similar thin-edged knives will use the preset angle and the polish stage. Owners of heavier Western-style knives or single-bevel blades should choose a sharpener built for their edge.
Pros and cons
- Fixed fifteen degree Asian-style angle
- Diamond wheels hold their shape
- Two stages in one pass
- Works on serrated knives too
- Only one edge angle available
- Not described for single-bevel knives
- Short one year warranty
Performance notes
Diamond abrasive wheels turn in opposite directions as the blade is drawn through, which produces a burr-free edge. Crisscross action and the angle guide set the same bevel each pass, and micron-size diamond in the second stage polishes the edge.
