Abstract
A strip-shaped or reciprocating knife has at least ore elongated cutting blade (1) provided with a plurality of cutting teeth (2) and intermediate cutting gaps (5), the cutting teeth (2) being provided with additional, finer teeth (8). In order to achieve from beginning to end a smooth and clean cut of the goods to be cut, the additional teeth (8) are produced by providing opposite tooth spaces (9) on both sides of the knife, arranged so close to one another that sharp teeth (12) are formed between the spaces. The additional teeth provided on both sides of the knife form a sharp cutting edge which is symmetrically arranged on both sides of the knife and extends over the cutting teeth (2).
