Abstract: Various embodiments relate to a vibration reduction mechanism for a hand operated striking tool. The vibration reduction mechanism includes a collar coupled to a portion of a handle of the hand-operated striking tool; at least one sleeve interposed over the collar; and at least one pin interconnecting the collar to the handle, wherein the at least one pin retains a position of the collar near a first end of the handle.

Abstract: A system that can be used to provide highly controlled thermal therapy and compression to both cool and heat a skin surface and a joint and surrounding tissue below the skin surface is provided. The system includes a joint conforming wrap; a power supply module for supply power to the joint conforming wrap and a cable operably coupling the wrap and the power supply module. The joint conforming wrap and power supply module include opposing thermoelectric modules. The joint conforming wrap is designed to provide heat transfer processes to the body of a patient to warm or cool the skin and a joint and surrounding tissue disposed under the skin.

Abstract: A hand tool includes a first jaw; a second jaw rotatably coupled to the first jaw, the second jaw including a first set of projections and a first bearing surface, the first bearing surface having a first curvature; and a lever coupled to the first jaw, the lever including a second set of projections and a second bearing surface, the second bearing surface having a second curvature. During a movement of the first and second jaws from a full open position to a full close position, the first and second sets of projections are at least partially engaged to prevent a slippage between the first and second bearing surfaces that are in a rolling contact during the movement of the first and second jaws from the full open position to the full close position.

Abstract: A utility knife includes a blade carrier configured to releasably couple to a blade; and a blade retention mechanism coupled to the blade carrier. The blade retention mechanism includes a first actuator; and a second actuator coupled to the first actuator, wherein an actuation of the first actuator permits the second actuator to move from a locked position to an unlocked position for the blade.
