Claim:
A cutting knife of a size which is difficult to manipulate with a bare hand and which is adapted for use with a chip-removing cutting tool, the cutting knife adapted to be replaceably held in a knife window of a rotary-driven tool shaft of a base body of the cutting tool, wherein at least one knife holder is connected to the cutting knife over a predetermined breaking point, and is configured to be grasped by the bare hand to assist with manipulation of the cutting knife, and is further configured to be broken off of the cutting knife at the breaking point and discarded once the cutting knife has been positioned in the knife window and prior to use of the cutting knife, thereby eliminating any need for a grasping tool to manipulate the cutting knife, the cutting knife further including an indentation in an upper edge thereof and between a cutting edge of the cutting knife and the breaking point, which is adapted to receive a tip of a spring biased pin in the tool shaft for securing the cutting knife in the knife window.
