The Fury Kubotan is a 5.75 inch self defense keychain with aluminum construction. Based on a classic self-defense keychain, this is a close-quarter weapon with a tapered pressure tip. It is essentially a derivation of the yawara stick, slightly thicker or the same size as a marker pen. Attached with a keyring for convenience and concealment, it appears as an innocuous key fob to the untrained eye.
