Coins have been used for concealment for quite some time. This unique version adds an additional layer of security and concealment due to it having both a “heads” and “tails” side to it unlike traditionally made ones with the blade still exposed on one side.

To deploy the blade, run your fingernail along the nickel's side clockwise with the "heads" side up, and the blade pivots out ready for use. The coin provides a solid grip handle. Weight: 0.18 oz. Made in USA.
