ABSTRACT:
A tool includes a solid block body unitary with a plurality of equidistantly spaced-apart blades which project from the body in the same direction, each blade having flat planar opposed faces with the faces of all of the blades being parallel to one another. The faces of each blade are chamfered at the distal ends thereof and are spaced apart by a pair of opposed parallel side surfaces, each inclined to the planes of the faces at an angle which approximates the complement of the helix angle of an associated spring, to facilitate insertion of the blades between the spring convolutions when the spring is extended, to maintain it in its extended condition.
