  • Patent number: 8732956
    Abstract: A safety mechanism for a utility knife is provided to prevent more than one retraction of the blade shield for each trigger actuation. A separable linkage extends between an actuator and a strut, and has a seat member and a deflecting member that are linked together when the actuator is not depressed and the strut is in the safety position blocking the retraction of the shield. The separable linkage is configured to transmit the pressing action of the actuator to the strut to disengage it from the bracket. The separable linkage is configured to delink as the shield retracts. If the actuator continues to be pressed in after the shield returns from being retracted, the safety mechanism prevents relinking of the seat member and the deflecting member, due to the deflecting member being deflected away from the seat member in a substantially longitudinal direction.

  • Patent number: 8683702
    Abstract: A folding knife capable of preventing automatic folding, which includes a handle having first, second and third plates, and a blade pivotally connected between the first and second plates by a pivot. The second plate is provided with a resilient stopper having a first end fixed to the second plate and a second end extending toward the first plate in a slanting manner. The third plate has one side corresponding in position to the second plate and concavely provided with an engaging hole. When the blade is fully rotated out of the handle, the second end of the resilient stopper presses against one end of the blade and thereby keeps the blade fully rotated out of the handle. Thus, when a force applied to the blade is excessively large, the resilient stopper will not be shifted away from the position against the blade.
