  • Patent number: 6058600
    Abstract: A tool for wire termination is disclosed in which the tool is fabricated from a pair of stamped tool ends, each with a working end and a tongue at the opposite end. The tongues are shaped with non circular, e.g., semi octagonal cross sections such that when the tongues are overlaid, they present a generally non circular, e.g., octagonal cross section region between the two working ends of the tool. A series of washers each with corresponding non circular shaped bores are strung on the tongues before the two tongues are overlaid. The assembly is then staked or otherwise secured together into a rigid structure. The method for producing the double ended tool as described above is also disclosed. The tool is to be secured in a bore of a handle by bayonet fastening using grooves in the washer stack. The tool is double ended for reversibility. The staking step may include use of a punch press die to upset the ends of the tongues to secure the washers.
