Abstract

A draw cut utility knife includes an elongated handle and a head holding a blade. The handle defines a thin central portion surrounded by a flange extending around its perimeter, the central portion aligning with the blade. The head has a rounded edge from which the blade protrudes, and is formed around the blade in a manner permanently embedding it in the head. The central portion may have cut outs for reduced weight, and the head preferably includes a thickened portion for holding the blade adjacent a centrally located cut out which accommodates a user'"'"'s finger. A second blade may be secured to another thickened portion of the head opposite the first blade, both blades permanently secured in the head with a rearward sharpened edge allowing the knife to be safely drawn toward a user and easily guided for a precision cut.

Claims
