Abstract
Abstract A wire stripper having a pair of relatively movable jaws provided with a plurality of thin blade-like members mounted on spring arms so that they may flex, and move relative to one another when closed around a piece of metal such as a wire. The spring means is such that the blade-like members will sever any electrical insulation around such wire, but will not sever the wire.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
Apparatus for cutting and stripping insulation or the like jacket material from a hard core member such as electrical wire or the like and comprising: a pair of jaw members adapted for movement towards and away from one another; handle means connected to said jaw members, for operatively moving said jaw members as aforesaid; a plurality of thin blade-like member hingeably mounted in side by side relation on respective said jaw members, in opposition to one another; cutting edge means on said blade-like members, arranged in opposition to one another, and adapted to be closed together when said apparatus is not in use; and spring means normally urging said blade-like members into a predetermined extended position, and being yieldable under stress, by contact between said cutting edge means and a hard core member as aforesaid, to permit said blade-like members to move into a retracted position.
