  • Patent number: 5964132
    Abstract: A multi-purpose utility tool, having a handle, a shaft and a locking and release mechanism. The handle defines a centrally located opening. The shaft has a first end and a second end and is to be slidably positioned within said centrally located opening. The locking and release mechanism locks the handle upon the shaft in first position and a second position. The first position allows the first end to be exposed for use while the second end is secured within the handle. The second position allows the second end to be exposed for use while the first end is secured within the handle. A handle stop portion extends from the handle towards the shaft. A shaft stop member extends outwardly from the shaft. The handle stop portion allows the shaft stop member and the shaft to be slidably positioned between a pair of limits of movement. The limits of movement include the first and second locking positions.
