Designed for carbon, aluminum and composite arrow shafts, it cleans and precision-squares the nock end of fletched or unfletched arrows for optimal Lumenok function and accuracy. Made of aircraft-grade, hard-anodized aluminum for durability and mounts easily to a bow bench with two screws. Includes four, self-adhesive abrasive discs.
The FAST tool is very easy to use and by using it a couple of my arrows no longer wobble when spin testing them. They apparently had squaring issues at the point and nock end. This tool is also very easy to use with fletched arrows.
