Abstract
A compound motion cutting device for cutting a work piece includes a tubular member having first and second ends, a pair of operating members and a drive rod having first and second ends and extending longitudinally into the tubular member. One of the operating members is secured to the first end of the tubular member and the first end of the drive rod is secured to the other of the operating members. An anvil is supported proximate the second end of the tubular member and includes a surface for supporting the work piece and a slot extending through the support surface. A cutting member includes a first end pivotally attached to the second end of the drive rod and a cam slot extending laterally therethrough. A pin is supported proximate the second end of the tubular member an extends through the cam slot in the cutting member. Movement of the operating members relative to each other in one direction causes the drive rod to move the cutting member in a first longitudinal direction and the pin and cutting member cam slot cooperate to simultaneously rotate the cutting member toward the anvil and to extend at least partially into the anvil slot to cut the work piece with a combined lon…
