Apparatuses, systems, and methods in which a utility knife includes a blade cover that is movable from a locked position to an unlocked position relative to at least one of a blade cartridge, a blade holder, and a tool handle are provided. When the blade cover is in an unlocked position, the blade cover can advantageously be moved from a blade covering configuration to a blade exposing configuration.

Blade cartridges and lockable safety covers

Apparatuses, systems, and methods in which a utility knife includes a hook-type cutter, and at least one of a blade tip cap and a blade cover that is movable relative to a blade or blade cartridge. Contemplated blade tip caps can be fixedly, removably or movably attached to the blade or other portion of a utility knife cartridge. Contemplated blade covers can move from a blade covering configuration to a blade exposing configuration.

Control panel box

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.

Safety locking mechanism for a utility knife

A cutting apparatus has a unidirectionally-locking blade cover that automatically snaps back over the exposed blade after each cut, and a dependent, index finger operated unlocking trigger.
