Japanese Patent JP2879279

Abstract:
A safety utility knife has a weighted pawl which, upon a slip of the knife, disengages from a blade holder to allow the latter to be retracted by a spring. The tooth of the blade holder engages the blocking surface of the pawl with only line or point contact and the blocking surface itself is tangential to a circle centered on the pawl pivot axis. The pawl spring is a coil spring extending in the direction of displacement of the blade holder and generally corresponds to the retraction spring.
