Abrégé

Improved bits for removal of staples and fabric for re-upholstering, one bit having an elongated shaft, proximal end, and distal working end. The proximal end is for insertion into a power tool. The working end includes a blade wider than the shaft and a plurality of beveled teeth. The bottom section of the tool has a longitudinally cambered bottom surface curved upwardly optimizing the striking, removal action. The blade end is transversely cambered, and converging in depth. The designs create tangential application of forces as opposed to only direct linear application. Another embodiment provides a non-symmetrical bit having a distal working end and chisel-type head that transitions into a curved side section, and an opposing straight angled side section. The bit is longitudinally cambered on the bottom surface, for separating legs of the staple without severing them, or snapping legs off from the staple crown.
