Abstract:
A tool for archery broadheads or other fasteners is provided including an engagement end having an aperture, socket or drive feature to accommodate the broadhead or engage a fastener. The tool is constructed at least partially from an elastomeric material. Upon application of a moment to the tool by a user, part of the tool deforms or twists so that indicia elements move relative to one another and output torque or moment information to a user based on the spatial orientation of the indicia elements relative to one another.
