Abstract
A laminated blade assembly including a stationary blade and a pair of insulation supports and a movable blade and a pair of insulation supports with each blade sandwiched between a pair of supports. Semi-circular grooves formed in the insulation supports and smaller semi-circular grooves formed in blades in alignment with the insulation support grooves creating circular grooves to support and cut the insulation when the stationary and movable blades come together. The support semi-circular grooves of one of the stationary and movable insulation supports are located with their peripheries tangent to a straight line which is not parallel to the center lines of the blade semi-circular grooves.
