The mandible is pivotally mounted on a vertical member of an inverted L-shaped frame which also includes a horizontally-disposed stabilizing element. The blade is secured between the vertical member and stabilizing element. The inverted L-shaped frame is secured to a rigid frame and extends forwardly thereof, the rigid frame including laterally extending balancing members for the device. Additional features of a locking means for the device when not in use, of a safety shield for the body and eyes against flying plastic fragments, and trough and guide for tubing seated in the channel, are provided.

A device for severing plastic tubing or the like comprising

a rigid frame,
an inverted L-shaped frame securely mounted upon said rigid frame and extending in a forwardly direction thereon,
said L-shaped frame including a horizontally disposed stabilizer and a pair of spaced vertically disposed members proximate the upper ends of and between which said stabilizer is secured, whereby said stabilizer extends forwardly relatively to said rigid frame,
cutting means including a singular blade and being securely mounted to and proximate a forward end of said stabilizer and to and proximate a lower end of said pair of spaced vertically disposed members whereby said blade is exposed in a generally forward direction relative to said rigid frame,
balancing members included in and extending laterally of said rigid frame and being disposed generally below said pair of spaced vertically disposed members, and
a mandible including a channel therein and being pivotally mounted upon said pair of vertically disposed members whereby the channel cooperatively acts with said singular blade in operation of the device.
