发明名称 Pocket sharpener for knives
摘要 A unitary pocket sharpener for knives is constructed from first and second overlaid metal discs each having a section with a straight edge, the edges being mutually arranged to form a wedge-shaped gap of approximately 40 DEG . On each straight edge is brazed a rectangular carbide tooth, longitudinally positioned on opposed segments of the straight edges such that the two juxtaposed teeth cross forming a similar wedge-shaped gap with a narrow space between the crossed teeth. The teeth each have a compound-beveled sharpening edge which respectively engage each side of a knife blade that is lodged in the small gap and drawn across the teeth in a uniform stroke for sharpening the knife.
