Blade with wave profile, method for grinding such a blade, and knife with such a blade

Abstract

The present invention relates to a blade (3) with a wave profile, a method for grinding such a blade (3) and a knife (1) with such a blade (3).In order to be able to grind the blade (3) better and more easily with available grinding equipment than with previously known solutions, the blade (3) according to the invention comprises an edge with a wave profile extending along the edge, wherein the wave profile has trough elements (4) for forming troughs and crest elements (5) for forming crests (5) projecting above the troughs, wherein each crest element (5) tapers in cross-section perpendicular to the blade blade in a wedge shape towards the tip in order to form a linear cutting edge section (5a) at the tip, wherein the linear cutting edge sections (5a) and the adjacent cutting flanks (5b) of the crest elements (5) are aligned with each other, so that the cutting flanks (5b) of the crest elements (5) can be ground in a continuous movement along the edge with a grinding device (6) having a flat grinding surface, in particular a roller grinder.
