Our next item is quite a multi-purpose utility and self-defense tool; the G-JMD EDC Self Defense Spike. This item is designed to be held single-handed and provide a hard and sharp striking edge similar to that of a flat head screw driver combined with a fist pack. The weight is 36g, its length from tip to end measures 90mm, and is made of stainless steel. It provides additional uses as an interior angle wrench, bottle opener, and screwdriver. The G-JMD EDC Self Defense Spike is a self-defense weapon disguised as a multi-tool.
