In certain aspects, the coupling mechanism 550 may further include a spring 572 biasing the carrier 554 toward the first position. The spring 572 may be a compression spring contacting the carrier 554 and the first handle 504 such that the carrier 554 is biased toward the first position. Accordingly, the carrier 554 remains in the first position unless force is applied to the carrier 554 or flashlight 530 to overcome the resistance of the spring 572 and move the carrier 554 to the second position. In some aspects, the first handle 504 may include an activation protrusion 576 that contacts the activation button 540 of the flashlight 530 when the carrier 554 is in the second position. Such contact may activate the activation button 540 such that the flashlight 530 provides light or stops providing light. In this manner, the coupling mechanism 550 may incorporate the flashlight into the multipurpose tool 500, while allowing for quick activation or deactivation of the flashlight 530 when the flashlight is coupled to the first handle 504. Furthermore, the coupling mechanism may allow the flashlight 530 to be activated or deactivated when the first handle 504 is in the open position or the closed position.
