The Self Defense Spear card is jam-packed with useful tools to help you out of several different tough situations. This handy tool fits into a wallet but contains enough small gear to fill a small bag. The tool itself is as small as a credit card, 1 millimeter thick, and 100% made in the USA. When deployed, this tool includes a spear tool for self-defense, tweezers, 1⁄4” bit driver, fishing lure, saw, 5 fishing hooks, arrowhead, and 2 sewing needles. One side of the tool has an adhesive back, which allows you to attach it to any flat surface and reuse tools several times.
