Abstract
A knife insert for use with a knife holder of a grinder, such as a meat grinder, is adapted to be positioned within a slot formed in the knife holder. The knife insert extends outwardly from the outer end of the knife holder, and a beveled edge is formed adjacent the outer end of the knife insert. The beveled edge is adapted to be engaged by a punch, which is struck such as by a hammer to dislodge the knife insert from the knife holder when it is desired to change knife inserts. The beveled edge enables the punch to be held at an angle relative to the knife holder and the adjacent components of the grinder, to allow the punch to easily be held in place. The hammer, which is used to apply the striking force to the punch, can easily be swung clear of the components of the grinder head to facilitate easy and quick removal of the knife insert.
