Abstract
Abstract A bow-and-arrow accessory of the type stabilizing a bow when attached thereto has a detachable portion for removal of embedded arrow points, that includes a straight rod with a set-screw equipped weight. The weight is slidable on the straight rod for adjustably varying the moment arm of the weight when the rod is attached to a bow. The weight is also slidable as a hammer against an anvil on a first end of the rod for axially with-drawing an embedded arrow point when the second end of the rod is attached to an embedded arrow point. The hammer action results in axial withdrawal and so eliminates dangers of damaging arrow points by wrenching, rocking or prying, and lowers risk of slipping and straining injury to the person removing an embedded arrow point.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
In a system for stablizing a bow and for withdrawing embedded arrow points of the type having screw threads for attachment to arrow shafts, said system including a rod, a bow stabilization weight on the rod with the rod providing a moment arm for the weight when the weight is mounted to a bow, means for mounting the rod to a bow, and internal screw threads at a first end of the rod for attaching the rod to screw threads of an arrow point; the improvement comprising: said rod having an anvil portion at a second end of the rod, said weight being slidable in position on the rod between the means for mounting and the anvil portion for varying the moment arm of said weight when the rod is mounted on a bow, and said weight being slidable on the rod for hammering on said anvil portion for withdrawing an embedded arrow point when the rod is attached to an embedded arrow point by said screw threads.
