Safety blade for utility knife

Image Number 2 for United States Patent #5337482.

A blade for a utility knife is provided which has a trapezoidal shape with a cutting edge and a pair of side edges which converge towards a blunt back edge. A safety edge joins each of the side edges with the cutting edges. The safety edges intersect with the cutting edge at an obtuse angle and provide substantially blunt surfaces. Safety corners are formed at intersections of the safety edges and the side edges. The safety corners are disposed at the outermost distal ends of the blade relative to the cutting edge. Cutting corners are formed at the intersections of the safety edges and the cutting edge. The cutting corners are disposed inwardly along the cutting edge relative the safety corners. This way, inadvertent contact between an operator and a safety edge would not be likely to cause injury since the safety corners would be contacted first.
