Abstract
A switchblade includes a casing that defines a cavity and a blade having a cutting edge. The blade has a retracted position in which the cutting edge is inside the cavity and a deployed position in which the cutting edge is outside of the cavity. A spring is operably connected to the blade to bias the blade to the deployed position. An actuator extends through at least a portion of the casing and has a hold position that engages with the blade to prevent movement of the blade with respect to the casing and a release position that permits movement of the blade with respect to the casing. A safety is operably connected to the actuator and has a lock position that prevents operation of the actuator and an unlock position that permits operation of the actuator.
