ABSTRACT:
A utility blade especially adapted for a roofing knife. The blade is fabricated from a flat, thin blank of metallic material and has a square central mounting hole for mounting in a conventional roofing knife. A first end of the blade is configured with a curvilinear, sharpened hook on one side and a V-shaped sharpened cutting component on the other side. The V-shaped sharpened cutting component terminates into a sharpened point. This arrangement is effective to give a user the advantage of having two different type cutting surfaces in one blade.
