Abstract
The present utility knife provides a uniquely improved safety mechanism that increases safety, reliability, and reduces the cost of manufacturing. A shield is locked over the blade by a strut braced between the shield and a stop within the housing. The strut is biased to the locked position by an integrally molded sinuous spring that is designed to force the strut into engagement with the stop and to force the shield to cover the blade, allowing just one cut per actuator pull. The stop structure checks the motion of the strut when locked and closely guides the movement of the strut when unlocked through use of an L-shaped channel. These features reduce the complexity of the safety knife and increase the reliability of the safety mechanism under rough conditions.
