Overview
A two stage self-sharpening system is built into this Wiltshire Staysharp utility knife, so the edge can be refreshed between uses. A slim scabbard allows storage in a kitchen drawer, and the triple rivet handle is shaped for comfort and control.
The reason to buy it is an edge that can be refreshed with the sharpener built in, backed by a long guarantee, on a slim knife that fits a drawer. The limitation is the contradictory material data and the lack of a stated hardness or edge angle.
Who it's for
Home cooks who slice delicate fruit, small vegetables and herbs, and want a drawer-friendly knife with sharpening built in, are the match. Those who need a long chef's blade, or clear steel and hardness details, should look elsewhere.
Pros and cons
- Built-in two stage sharpening system
- Slim scabbard stores in a drawer
- Triple rivet ergonomic handle
- Long guarantee period
- Steel details contradict each other
- Edge angle and hardness not listed
Performance notes
The maker describes a patented two stage self-sharpening system meant to restore the edge on demand, so sharpness depends on how often it is used. A plain edge slices fruit, small vegetables and herbs, and the low weight eases repeated cuts. The listing gives no hardness figure, so edge life is the maker's claim rather than a measured spec.
