Abstract: A suppressor for a firearm includes a casing that defines an axis, and a baffle is in the casing. The baffle has upstream and downstream surfaces and a frustoconical surface between the upstream and downstream surfaces. The baffle defines a fluid pathway through the upstream, downstream, and frustoconical surfaces along the axis. An annular chamber is located between the frustoconical surface and the casing. A first contoured wall extends upstream a first height from the upstream surface, and the first contoured wall defines a perimeter around a first damping well in the upstream surface. A second contoured wall extends upstream a second height from the upstream surface, and the second contoured wall defines a perimeter around a second damping well in the upstream surface. The first height of the first contoured wall is larger than the second height of the second contoured wall.

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.
