ABSTRACT:
A chipper knife includes a pair of elongate blade portions integrally joined at a midplane which longitudinally bisects the blade. The blade portions are symmetrical and have inner and outer surfaces. The outer surface intersects the midplane at an acute angle and the inner surface intersects the midplane at a lesser acute angle. The inner and outer surfaces therefore diverge from each other as they extend outward from the midplane. The outer surface of each blade portion terminates in a cutting edge. A mounting for the knife is carried on a chipper disc and includes a base for supporting the inner surfaces of the blade portion with a cutting edge thereof disposed outwardly from the disc surface and a hold down plate engaging an outer surface of the blade to secure the knife to the mounting.
