Abstract: The pruning tool incorporates the functions of a pruning shear and a pruning saw into a single handheld tool. The pruning tool includes a conventional pruning shear and a folding saw blade that pivotally deploys from a stowed position within the handle to an extended operational position. The pruning tool also includes an opening assist mechanism that allows the saw blade to be partially moved under spring tension from the locked stowed position within the handle.

Abstract: A multi-function hand tool with a pivotally collapsible jaw-type tool that has a jaw lock which mechanically prevents the jaw-type tool from collapse. The jaw lock mechanism is contained within the jaw pivot joint of the jaw-type tool, and may be partially extended as a push button to prevent unwanted handle collapse. A plurality of blades are pivotally attached to the opposite end of the multi-function tool, which has a blade locking mechanism wherein the blade lock is pivoted about an axis located distal to the blade fastener/pivot axis. Each handle of the multi-function tool may be made of two individual handle halves that unite to form the handle, but that provide very precise tensioning, or the handles may be of a single channel shape using an infinitely adjustable threaded fastener and sleeve to provide precise adjustment of the multiple blades.

Abstract: A multi-function tool includes a head and a pair of handles. The head has a first jaw and a second jaw, each having a working portion and a tang. The handles have a folded configuration and an unfolded configuration. A spring in the head biases the working portions apart from one another such that the handles are biased in an open position when the handles are in the unfolded configuration and the handles are biased in a closed position when the handles are in the folded configuration.

Abstract: A multi-function tool includes a head, a pair of handles, and a plurality of ancillary tools. The head and tools are stored within the handles in a folded configuration. The ancillary tools are coupled to an interchangeable cartridge that resides within one or both of the handles. A wedge lock prevents a fully opened ancillary tool from closing unless the wedge lock is manually disengaged.

Abstract: A multi-function tool includes two channel-shaped handles having a first side wall and a second side wall forming a channel therebetween. An interlocking mechanism includes a first plate extending from the first side wall, and a second plate extending from the second side wall. At least one of the first plates has a periphery with a notch formed therein. At least one of the second side walls has a post extending therefrom. Each handle is releasably engageable by alignment of at least one post of one of the handles with at least one notch of the other handle. The multi-function tool also includes an interchangeable implement including a pair of handles with implement engaging means. An axle assembly extends transversely through the openings formed in the first and second plates and includes a first end member, a second end member, a pair of buttons and a spring. The spring is disposed between each of the buttons to bias the buttons into engagement with the end members.

Abstract: A multi-function tool includes a cross-jaw module removably attached to a pair of channel-shaped handles with a pair of clips. Each clip removably attaching the tang of each jaw of the cross-jaw module to one of the handles. The multi-function tool also includes a spring biased wedge lock to positively lock a plurality of pivotal attached ancillary implements in an open position. An anti-rotational washer located between adjacent implements prevents rotation of a non-selected implement. The washers include a protrusion that is received in a slot in the handle.

Abstract: A knife having a blade rotatably coupled to a handle and lockable in an extended or a folded configuration is provided. A device for locking the extended blade against clockwise rotation and a separate device for locking the extended blade against counterclockwise rotation are provided. In one embodiment, one of these mechanisms is a key and keyway device and the other of these mechanisms is an adjustable stop device, preferably adjustable by a set screw.

Abstract: The frame of a personal, folding knife forms a compartment for receiving a knife blade having a hub pivoted to turn on the frame about an axis spanning the compartment. A locking block is manually slidable on the frame. A spring urges the lock block toward engagement in a notch in the blade hub.

Abstract: A cork extractor for a cork in a bottle has a frame adapted to engage the bottle end around the axis of the cork and has a rod slidable and rotatable in the frame in line with the cork. A lever pivoted on the frame has a yielding pawl adapted individually to engage and successively to ride over each one of a series of stops on the rod, in this way incrementally extracting the cork with each actuation of the lever.

Abstract: The forks of a bicycle receive an axle having threaded ends. A tube surrounds the axle and carries ball bearings on which a wheel housing is rotatable with a space between the tube and the housing. Specially shaped seals engage the wheel housing and the tube between the ball bearings to keep lubricant out of the space between the seals. A special lever lock on one end of the axle cooperates with a nut on the other end of the axle to draw together the parts engaged with the axle, the tube and the housing.
