A tool such as a knife or other hand tool has only two pieces, a handle and a blade or other implement. The blade is movable from a fully retracted position to an extended position and the blade may be locked in both the retracted and extended positions.

Two-piece hand tool

Knives () each include a handle () having a blade () pivotally attached to the handle. The blade is movable between a closed position in which it is received within a groove () of the handle and an open position. The blade has a working portion () and a tang portion (), which remains within the groove when the blade is in its open position. A locking pin () extends transversely of the handle and blade and is movable along a pair of elongated openings (), and engages the tang portion () of the blade to lock the blade in its open position. A spring () biases the locking pin toward the tang.

Folding pocket knife with a lock

A folding tool such as a knife or multitool and the like has a resilient lever arm formed in a body portion. A blade pivotally connected to the body is movable between closed and open positions. A blade locking pin is carried on the lever arm, and in the normal resting position the blade locking pin engages the blade. When the blade is in the open position the lever arm biases the locking pin into locking engagement with a notch formed in the blade tang, thereby locking the blade in the open position. Actuating the lever arm disengages the locking pin from the blade, allowing the blade to be moved into the closed position. The blade may have a second notch or hole formed in the tang for engagement of the blade locking pin when the blade is closed, thereby locking the blade into the closed position.

Folding tool locking mechanism

Knives ( ) each include a handle ( ) having a blade ( ) pivotally attached to the handle. The blade is movable between a closed posiiton in which it is received within a groove ( ) of the handle and an open position. The blade has a working portion ( ) and a tang portion ( ), which remains within the groove when the blade is in its open position. A locking pin ( ) extends transversely of the handle and blade and is movable along a pair of elongated openings ( ), and engages the tang portion ( ) of the blade to lock the blade in its open position. A spring ( ) biases the locking pin toward the tang.

An actuator mechanism is defined by a lever arm that is integrally connected to resilient spring members. The lever arm is movable between first and second positions and is normally biased into the first position in which the actuator may engage an adjacent member, for example to provide a fluid-tight sealing relationship of to lock the adjacent member in a stationary position relative to the lever arm. Movement of the lever arm into the second position releases the engagement with the adjacent member. In one embodiment the actuator is defined by a pair of overlapping, oppositely oriented slots cut into a monolithic member to define both the lever arm and the spring members. The lever arm rocks in a teeter-toter fashion when actuated and both ends of the lever arm can be utilized to perform work.

Knives ( ) each include a handle ( ) having a blade ( ) pivotally attached to the handle. The blade is movable between a closed position in which it is received within a groove ( ) of the handle and an open position. The blade has a working portion ( ) and a tang portion ( ), which remains within the groove when the blade is in its open position. A locking pin ( ) extends transversely of the handle and blade and is movable along a pair of elongated openings ( ), and engages the tang portion ( ) of the blade to lock the blade in its open position. A spring ( ) biases the locking pin toward the tang. In another tool ( ), multiple tool blades ( and ) are provided in a handle ( ) defining a wider groove ( ), and a locking pin ( ) movable along elongate openings ( ) can lock a selected tool blade in an open position. A pair of the handles ( ) can be attached pivotally to handle stubs ( ) of a pair of pliers, using the same sort of locking mechanism. An automatic opening mechanism in another tool utilizes a pair of coiled springs that urge a blade into an open position. A locking member locks the blade in the open and closed positions.

Folding tool with a lock and automatic opener

A folding tool includes an elongate handle and a blade pivotally attached to the handle. The blade is movable between a closed position in which it is received within a groove, between the side walls of the handle, and an open position in which the blade extends away from the handle and is exposed. The blade has a tang portion which is received within the groove of the handle when the blade is in its open position. A blade locking pin is part of a sliding lock assembly and extends generally transversely with respect to the length of the handle and blade. The pin is movable along a pair of elongate holes, between a first position in which the pin engages the tang portion to lock the blade in its open position and a second position in which the pin is spaced away from the tang and allows the blade to move to its closed position. A spring is biases the pin to its first position and is further provided for manually moving the pin to its second position from its biased first position.

Portion of a knife blade

A pocket knife includes a handle having a body portion and a blade pivotally attached to the body portion of the handle. The blade is movable between a closed position in which the blade is received within a groove of the handle and an open position in which the blade extends away from the handle and is exposed. The blade has a blade portion and a tang portion which is received within the groove of the handle when the blade is in its open position. A pin extends in a direction generally transverse with respect to the direction of the handle and blade, and is movable between a first position in which the pin engages the tang portion of blade for locking the blade in its open position, and a second position in which the pin is spaced away from the tang portion of the blade for allowing the blade to move to its closed position. A spring is provided for biasing the pin to its first position. Moreover, a sliding lock assembly is further provided for manually moving the pin to its second position from its biased first position.
