<p>The pocket sharpener (10) is constructed from a pair of overlaid metal plates (12,14) each having a section with a substantially straight edge (18), the edges being mutually arranged to form a wedge-shaped gap (20) of approximately 40 DEG . On each straight edge (18) is brazed a rectangular carbide tooth (26,28), longitudinally positioned on opposed segments of the straight edges such that the two juxtaposed teeth cross forming a similar but smaller wedge-shaped gap (30) with a narrow space between the crossed teeth. The teeth each have a compound-bevelled sharpening edge for respectively engaging opposite sides of a knife blade that is lodged in the smaller gap (30) and drawn across the teeth in a uniform stroke for sharpening the knife. </p> |
