  • Patent number: 4815346
    Abstract: A multi-purpose portable and collapsible hand tool including a main barrel having a plurality of differing blades or bits. Each blade or bit is pivotally mounted on the barrel with at least one end cap closing off one end of the barrel where the blades or bits are pivotally connected to the barrel. The end cap is rotatably mounted to the respective barrel end and includes an elongated slot so that a blade or bit, normally disposed against the barrel and lying substantially parallel to the longitudinal axis of the barrel, is prevented from pivoting away from the barrel until the end cap preventing said pivoting is rotated to align its slot with a blade or bit so that the blade or bit may be pivoted away from the barrel to a position extending parallel to the longitudinal axis of said barrel, said end cap being rotatable to prevent said blade or bit from pivoting back against the barrel, i.e. to lock the blade or bit into operative position.
