Abstract: Cutting apparatus including an elongate knife shiftable between cutting and noncutting positions, and an elongate anvil having an arcuate striking surface against which the knife may strike. The anvil includes an elongate shaft having an arcuate lower surface which rests in an elongate cradle and is rotatable about its longitudinal axis. The upper surface of the shaft facing the knife has a resilient covering secured thereto. A rotator connected to the anvil is operable to produce random angular incremental rotation of the anvil between cutting strokes of the knife to present different cutting surfaces of the anvil to the knife. The support for the anvil includes a support member having a pair of oppositely facing, angularly disposed surfaces and a pair of holding blocks having angularly disposed surfaces which engage the surfaces of the support member.
