ABSTRACT:
The invention relates to a knife insert for tools with an oscillating head, preferably of the type used for cutting open rubber or adhesive beading strips around windscreens and having a cutting face bounded by one or a plurality of cutting edges. When producing such a knife, in order to be able to use less expensive material and in order to be able considerably to reduce the reciprocating movements of the shank when driven by a tool which performs oscillatory rotary movements, it is according to the invention proposed that the knife be angled over in an L-shape at right-angles to its cutting face, the cutting face forming a first leg of the L, and the second leg of the L which extends substantially at a right-angle from the cutting face comprising a connecting element for connection to an actuating tool.
