1. A bending tool configured for hand-held use, the bending tool comprising:
a drive device further comprising:
an outer shell further comprising an outer shell first end and an outer shell second end; and
a movable member located at least partially inside the outer shell and configured to move relative to the outer shell, the movable member further comprising a movable member first end and a movable member second end;
an elongate arm comprising an elongate arm first end and an elongate arm second end, the elongate arm further comprising:
a hollow shaft further comprising a hollow shaft first end, a hollow shaft second end, and a hollow shaft inner cavity; and
a bending head attached to the hollow shaft second end, the bending head further comprising:
a bending head first end and a bending head second end;
an open cavity at least partially defined between a first side wall, a first gap, a second side wall, a second gap, and an end side wall wherein the end side wall includes an indented section extending toward the bending head second end, and wherein the first gap is located between the first side wall and the end side wall, and wherein the second gap is located between the second side wall and the end wall; and
a passage extending from the bending head first end into the open cavity;
a rod comprising a rod first end and a rod second end wherein the rod first end is in contact with the movable member second end, wherein at least a portion of the rod is located inside the hollow shaft inner cavity, wherein the rod is configured to move inside the hollow shaft inner cavity, and wherein the rod second end extends through the passage and into the open cavity; and
a wedge member coupled to the rod second end and configured to fit inside and move inside the open cavity from a first position to a second position and from the second position to the first position, the wedge member further comprising a wedge bending surface facing the end side wall of the bending head, the wedge bending surface further comprising an outward facing central arch, a first indentation on a first side of the wedge member, a second indentation on a second side of the wedge member and spaced apart from the first indentation by the central arch, a raised first edge along the first side of the wedge member and spaced apart from the central arch by the first indentation, and a raised second edge along the second side of the wedge member and spaced apart from the central arch by the second indentation, wherein each of the first indentation and the second indentation are closer in distance than each of the central arch, the raised first edge, and the raised second edge to the rod second end, wherein the wedge member has a wedge bending plane perpendicular to the wedge bending surface and including a longitudinal centerline of the wedge bending surface, wherein each of the central arch, the first indention, the second indention, the raised first edge, and the raised second edge intersect the wedge bending plane.
