Abstract
A telescoping self-defense keychain includes a keyring attached on a swivel for tethering one or more keys. The keychain may also be used for self-defense or by police to control a suspect during arrest. The keychain has a telescoping member which may be extended to increase the overall length of the keychain to provide more effective use as a weapon. The telescoping member is held in the extended position by a flared end on the telescoping member which wedges into a swaged end of the handle. A leaf spring engages the flared end of the telescoping member to retain it in a retracted position.
