Abstract:
A cutting implement having a cutting end at its forward end and a handle end at its rearward end and having a top and a bottom, and capable of being operated one handed which comprises;(1) a bottom handle bent near its middle such that the forward end is lower than the rearward end, the bottom handle having a cutting blade protruding upward from its forward end and having a hinge at its rearward end; (2) a lever being rotatably affixed to said bottom handle at its rearward end at the hinge on said bottom handle, the lever having a cutting blade protruding downward from its forward end such that the sharp end of the cutting blade on said bottom handle meets the sharp end of the cutting blade on said lever; (3) a control arm rotatably affixed to said bottom handle just rearward of the cutting blade on said bottom handle, the control arm being of sufficient length that it may protrude upward above said lever; (4) a top handle positioned above said lever and being rotatably affixed to the end of said control arm opposite said bottom handle, the top handle being of sufficient length that the rearward end of said top handle ends near the rearward end of said bottom handle; and (5) a cam having two pivot points and being rotatably affixed at each of the two pivot points, one of the two pivot points being at the same point where said top handle is rotatably affixed to said control arm, the other of the two pivot points being a rotatable connection with said lever rearward of the the cutting blade on said lever; whereby the cam gives a mechanical advantage to an operator such that the operator may use the cutting implement with one hand to cut materials which would ordinarily require two hands to cut.
