Abstract

512,326. Sharpening knives. JAFFA, A. E. March 3, 1938, No. 6640. [Class 60] A sharpener for knives comprises a hardened steel &c. strip 10 having formed therein two or more teeth 11, 12, alternate teeth being set in opposite directions like the teeth of a saw, and the teeth being of such a length that they possess resiliency below the set portions; in sharpening, the knife edge is drawn longitudinally of the V formed by the teeth. The teeth may be curved and their surfaces may be grooved lengthwise, and saw cuts may be made to separate adjacent teeth. The uncut base portion of the strip may constitute or receive a holder or may be divided into two oppositely disposed flanges to be secured to a support. As shown in Fig. 4, the base of the sharpener is inserted in a groove 14 in a wooden or artificial resin holder 16, with the teeth in a recess 15, the walls 17 of which have therein slots 18 to guide the knife..In this construction a sharpener may be placed at each end of the holder. In a further form, the recess 15 is omitted and the transverse slot 18 has an enlarged part to receive the teeth.
