ABSTRACT:
A shear device includes a hand grip and a handle pivotally coupled together. A bar has one end pivotally coupled to the handle. A cutter blade has a middle portion pivotally coupled to the hand grip and has a pin secured to one end. A lever has one end pivotally coupled to the hand grip at a pivot rod and has the other end pivotally coupled to the bar at a pivot pole and has a groove formed in the middle portion for slidably engaging with the pin. The pin is disposed between the pivot pole and the pivot rod for allowing the cutter blade to be rotated with less force.
