The present invention relates to pivoted tools such as scissors, pliers, shears, and the like. More particularly, this invention is concerned with pivoted tools having a pair of elongated members and a pivotable joint. The pivotable joint comprises a pair of registering apertures cooperating with a self-compensating unitary pivot member. The pivot member, which is formed when the tool is in closed registered configuration, conforms with the apertures and engages the interior surfaces thereof.

A tool having a force applying end and an opposed working end disposed across a pivotable joint through which a working force may be transmitted, wherein said tool includes first and second elongated members, each having oppositely facing inner and outer surfaces, said members being disposed for cooperative engagement about said pivotable joint and further wherein said joint is comprised of: a) first and second registering apertures, one of each formed in a respective one of said elongated members, said apertures having respective first and second center lines generally normal to said surfaces, said center lines being misaligned by an eccentricity amount but in sufficient registration to permit said cooperative engagement; b) a unitary pivot member mechanically interlocked within one of said apertures; said pivot member having a head lying adjacent and effectively in contact with the outer surface of said second elongated member, and a shank projecting from said head through, and conforming with, said apertures into engagement with the interior surfaces thereof, said shank comprising a head portion having a longitudinal axis, said head portion conforming with said second aperture, said shank further comprising an end portion having a longitudinal axis, said end portion conforming with said first aperture and terminating at a point lying substantially proximate but below the juncture of said first aperture and the outer surface of said first member, said shank further including a threaded bore; and c) a threaded fastener received in said bore for controlling a compressive force applied to said joint; whereby said head portion longitudinal axis is coincident with the second center line and said end portion longitudinal axis is coincident with the first center line so that the head portion longitudinal axis and the end portion longitudinal axis are misaligned by an amount substantially equal to said eccentricity amount.
