ABSTRACT:
A hinge pin removal tool for removing a head capped pin from a knuckled door hinge. The hinge pin removal tool comprises an elongate shaft, a generally planar tool head attached to the elongated shaft which extends therefrom. The tool head includes a first and a second end. The tool head is attached to the elongate shaft proximate to the second end of the tool head. The tool head further includes a tapered chisel edge disposed at the tool head first end, and an elongate pin punch disposed orthogonally to the tool head intermediate the chisel edge of the first end and the second end. The tool head may be disposed orthogonally to the elongate shaft. In a second embodiment the tool head and elongate shaft are substantially collinear. The hinge pin removal tool may further include an open slot disposed in the chisel edge which extends inwardly therefrom toward the second end of the tool head. The slot width is sized to accommodate a hinge pin shaft. The hinge pin removal tool shaft may include a first and a second end, wherein the first and second end each include a tool head attached thereto. In this version of the hinge pin removal tool, the two tool heads are disposed at opposite directions relative to each other. Each tool head includes a chisel edge and an elongate pin punch.
