  • Patent number: 6412130
    Abstract: A multi-tool with a handle formed to have a cross section that is S-shaped so that a foldable tool stored in the handle may be opened and closed independently of other selected operations for the multi-tool. The foldable tool is stored in a first pocket, facing away from an opposing handle, and an adjustment mechanism is stored in a second pocket, facing toward the opposing handle. A leaf spring is cut from an opposing wall of the first pocket, and biased so that the leaf spring moves to a blocking position at least partially within the first pocket when the foldable tool is in an open position. A post is mounted on the foldable tool and is exposed for engagement by a human hand to facilitate deployment of the foldable tool from its closed position to its open position. The S-shaped construction of the handle allows a flange to be incorporated as part of the handle without interfering with the foldability of the foldable tool stored in the first pocket of the handle.
    Type: Grant
