Abstract
A cutting mechanism for use with a strapping tool includes a cutter having a polygonal cross-sectional configuration, a plurality of cutting surfaces defining a pair of elongate cutting edges, and a plurality of retaining recessed. The cutting edges are an in-use edge and a spare edge. The cutter is engaged with a movable die holder having a support surface for the cutting body. The holder includes a slot defining a plurality of projections. The projections are configured so that the retaining recesses of the cutter fit within the support surface slot. The cutter is reversible on the die holder such that the in-use and spare cutting edges are interchangeable by rotation of the cutter.
