1. An apparatus for removing filament from a reel comprising:
a cylindrically shaped spool body with a first end and a second end opposite the first end, the body having a diameter, a length, a central axis extending through the first end and the second end, an outer circumferential surface, and a hole extending radially inward through the outer circumferential surface;
a shank extending outwardly perpendicular to the first end of the body and coaxially with the axis of the body, the shank being sized and shaped for functional communication with a chuck;
a second end cap that is sized and shaped to mate with and removably interconnect with the second end of the body, the second end cap having an inner circumferential surface and an opposing outer circumferential surface, and the inner circumferential surface of the second end cap defines a cavity, the cavity being sized and shaped such that when the second end cap is mated with the second end of the body, the cavity envelops the second end of the body and at least a portion of the outer circumferential surface of the body and the cavity coaxially aligns with the central axis of the body, the cavity having a diameter that is larger than the diameter of the body; and
an elongate tension arm having a length and fixedly interconnected at one end with the second end cap, the elongate tension arm being sized and shaped such that when the second end cap is mated with the second end of the body, the elongate tension arm is spacedly adjacent to the outer circumferential surface of the body.
