    • A hand weapon that appears to be an innocuous key carrying device is employed for self-defense. In a first preferred embodiment, the device includes a hollow handle having flexible cordage, typically a double cord, that passes through it to which a number of keys or other weighted objects are affixed via an attachment mechanism, usually a split-ring or similar mechanism. A spring-loaded plunger mechanism extending radially through a cross-section of the hollow handle pinches a portion of the flexible cordage in the interior of the hollow handle to hold it in position. A first position is where the attachment mechanism abuts a first end of the hollow handle. If an attacker threatens, the user depresses the spring-loaded plunger mechanism while slinging the first end with weighted objects affixed, typically keys, toward the attacker using a slashing movement. The weight of the keys aids in rapidly deploying the flexible cordage to a second position, which reaches full extension when the stop mechanism abuts the second end of the hollow handle. This action permits the keys to be hurled to and fro at an attacker. This self-defense device may be used for blocking and counterattacking the attacker.
