ABSTRACT:
A utility knife can be equipped with a removable blade protective guard structure to prevent the person from being cut when the knife is not in use. The guard structure includes a mounting element having a pivotable connection with an elongated guard element near the leading end of the knife handle. A torsion spring is coiled around the pivot shaft to normally urge the guard element to a position extending along the cutting edge of the blade. However, the guard element can be swung through an arc of about one hundred eighty degrees (180) to assume a position lying alongside a side edge of the knife handle, away from the cutter blade.
