Claim:
A jaw member for use in a metal demolition shears, said jaw member comprising: a jaw body with a cutting/shearing edge extending therealong; and an indexable wear plate/piercing tip insert that is attached at a front, nose portion of said jaw body, the wear plate/piercing tip insert comprising a metal insert body having a central region and two ends and a metal tip portion disposed at each of said two ends, each said tip portion protruding laterally with respect to a surface of said central region in the direction of a first side of said insert body so as to define an integral piercing tip that extends at least partially across the width of the front, nose portion of the jaw body, wherein a second side of said insert body that is opposite to said first side has a generally planar surface to define a wear surface of said wear plate/piercing tip insert, wherein each said tip portion has a shearing edge on said second side of said insert body and a piercing edge disposed at an angle relative to and intersecting with said shearing edge, said piercing edge extending at least partially across the width of the front, nose portion of the jaw body, wherein the geometric configuration of said wear plate/piercing tip insert is essentially the same in a first position and a second position, said second position being a position in which said wear plate/piercing tip insert is rotated about a pivot axis passing centrally through said wear plate/piercing tip insert, normal to said generally planar surface, wherein a non-worn or less worn portion of said wear surface and non-worn or less worn shearing and piercing edges can be presented for the metal demolition shear by rotating said wear plate/piercing tip insert about said pivot axis from said first position to said second position and reseating said insert body on said movable blade member, and wherein the cutting/shearing edge is provided by at least one blade insert member.
