Abstract: A folding multipurpose hand tool including folding pliers or scissors and other tool blades and bits. A pair of handles each has a pivot axle at each end. A base of each pliers jaw or scissors blade is mounted on the pivot axle at one end of a handle, allowing the handles to fold around the jaws to blades to a compact folded configuration of the tool. Each handle has frame side members with attached flanges. Elongate springs lie between the handle frame side members and fit around the flanges, rather than being riveted to the handle frame side members. The springs press against the base of each pliers jaw or other tool blade, to keep each in a folded position or support it in a deployed position. One end of a spring may be hooked around a spring retainer at one end of the handle. The pivot axles interconnect the handle frame side members and the jaws, blades, or tool bits.

Abstract: A folding multipurpose tool includes removable tweezers. The tweezers have a pair of opposed legs that are hooked over a pin extending through a tool storage pocket in a handle of the tool. The tweezers can pivot about said pin between a folded position within said pocket and an extended position outside of said pocket. One of the legs is thicker than the other and unable to pass through a passageway between the pin and the floor of the tool pocket. When the tweezers are in the extended position one of the legs may be slid into the pocket, disengaging the tweezers from the pin and enables the tweezer to be lifted out of the pocket. A generic implement with a hooked shaped base may be removed from a tool pocket in a similar manner.
