Abstract

A knife sharpener has at least two sharpening strips.
The sharpening strips are arranged to adjoin each other in the width direction and intersect with each other. The sharpening strips are elastically deformable and include spread portions, respectively. The spread portions stretch from the intersecting point to one ends of the strips and are splayed to form a V-shaped groove having a vertex angle.
The sharpener has abrasive surfaces formed on one surfaces of the spread portions, respectively. The abrasive surfaces form both side faces of the groove. The sharpener further has a fixing member fixing the other ends of the strips and stoppers brought into contact with the strips to limit maximum opening width of said groove. The abrasive surfaces are bent by the fixing member and stoppers to increase the vertex angle when a blade edge of a knife is sharpened in the groove.
