Abstract

686,668. Knives. PARKIN, C., PARKIN, H., and PARKIN F., [trading as PARKIN BROS.] Jan. 30, 1950 [Feb. 1, 1949], No. 2782/49. Class 30 [Also in Group XXII] In a knife blade, of the kind having spaced grooves near the cutting edge in one or both faces of the cutting blade, the grooves intersect the cutting edge forming curved lips which project into the opposite face of the blade. As shown, curved lips 7 project alternately into the faces 3, 4 of the blade 1 and are formed where the base 5 of each groove 2 intersects the cutting edge 6 by subjecting the blade to the action of the rounded edge of a grinding wheel. Before the groove is completed the blade is tilted from a position tangential to the wheel to increase the angle between it and the wheel and displace the thin web of material to form the curved, projecting lip.
