Paranoia or good planning — whatever the reason, this Fifty-Cent Escape Knife is a unique and potentially life-saving piece of kit. During a search, coins are the most overlooked items on a person, making this perfect for either carrying or pre-placement. A Japanese circular steel blade is housed in a case made from a split 50-cent piece — the real, official US currency — and is capable of cutting through rope, zip ties, or other non-metallic materials. The two halves are securely held together with a rubber o-ring in a channel around the coin's perimeter, with the coin itself providing a solid grip.
