The A.S.D. TM(a.k.a. Arrow Squaring Device) has been improving accuracy around the world. The Universal Cutting Tool is two tools in one. One side machines aluminum – the other carbon. With the purchase of a single package, the archer can machine, clean, and de-burr a variety of materials. The result – arrows, inserts, and bushings perfectly square to the arrowshaft providing more accurate shooting and more consistent grouping regardless of the brand of broadhead used.
