US Patent 11491667 Easily disassembled folding knife

A folding knife includes a blade, a handle, an actuation mechanism, and a switch. The handle includes first and second side portions. The blade is pivotably coupled to the first and second side portions. The actuation mechanism is coupled to the handle and is movable between engaged and disengaged configurations. In the engaged configuration, the actuation mechanism prevents relative movement between the first and second side portions of the handle in a first direction. In the disengaged configuration, the actuation mechanism allows relative movement between the first and second side portions of the handle in the first direction. The switch is coupled to the handle and the actuation mechanism. The switch is configured such that moving the switch along a first path retains the actuation mechanism in the engaged configuration and moving the switch along a second path moves the actuation mechanism between the engaged and disengaged configurations.
