Abstract: A folding knife can include a handle portion, a pivot element, a blade, a locking element, a cap, and a rotatable wheel. The handle portion can comprise a first side portion and a second side portion. The blade can pivot about the pivot element between an open position and a closed position. The locking element can prevent disassembly of the first and second side portions when the locking element is in a locked position and allow disassembly of the first and second side portions when the locking element is in an unlocked position. The cap can be coupled to the first side portion adjacent the locking element. The pivot element can extend into the cap. The rotatable wheel can be disposed between the first and second side portions and can rotated to selectively retain the first and second side portions together.

Abstract: 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.
