Title: Safety utility knife
Inventor: OKADA SHOJI
IPC: B26B1/08
Filed: 2001-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a safety utility knife of which the mechanism is simple, and of which safety is high.

However, when the utility knife is slid along the object, under a state wherein the distal end of the blade bites into the cutting object 50, the distal end of the blade is further pulled out from the small amount by the cutting objective. As a result, a blade protruding amount which is sufficient for cutting the cutting objective is obtained. The blade 20 is pulled back into the knife body by the urging means 30 when separated from the cutting object 50. Thus, the blade protruding amount from the utility knife body is kept under the small amount.
