Patent number: 6622328Abstract: 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.Type: GrantFiled: January 30, 2002Date of Patent: September 23, 2003Assignee: Leatherman Tool Group, Inc.Inventor: Benjamin C.
