Abstract: An easy to use power rotary shear is disclosed to facilitate cutting rigid and semi-rigid sheeted materials, such as rigid sheeted materials including the likes of metal roofing, or other rolled or formed sheet metal, sheeted semi-rigid plastics, fiberglass, and the like, as well as a method of making same, and a method of using it. This includes utilizing a portable single handed, weight balanced, smooth cutting power rotary shear. One specific preferred aspect has certain features including a v-shaped relief behind the rotary cutting blades that automatically separates the pieces generated by the cutting operation. Cutting rigid sheeted materials, especially large pieces, is made almost effortless with the inclusion of this motorized power rotary shear that can be operated with one hand, while holding the workpiece with the other hand.

Abstract: In the present invention, there is disclosed a pair of multi-level J-channel cutter shears, comprising a shear blade permanently attached to a handle and a stationary blade being pivotally attached to the shear blade, and wherein an L-shaped channel runs therethrough, creating at least an upper and a lower cutting edge, and wherein the stationary blade includes multi-level cutting surfaces defining the upper and lower cutting edges, and wherein the stationary blade is also attached to a handle.
