A folding knife in exemplary embodimentsTong comprises a handle portion, a blade, a locking cross-bolt, and a motion limiting member coupled to the handle. When the blade is in the closed position, the motion limiting member is in a first position that prevents the cross-bolt from moving to its locked position. When pivoting the blade to the open position, the motion limiting member moves to a second position that does not prevent the cross-bolt from moving to its locked position. A biased safety mechanism can also be used to block the cross-bolt from moving to an unlocked position.

Folding knife

A safety mechanism that protects against inadvertent closure of the blade of a folding knife. In one embodiment, the safety mechanism is implemented in a folding knife having a liner lock with a flexible, resilient locking element. The safety mechanism is movable between a safety position in which the safety mechanism interferes with movement of the flexible locking element to its unlocked position and a release position in which the locking element can be moved to its unlocked position for closing the blade. The safety mechanism is resiliently biased toward the safety position and is retained in this position unless sufficient pressure is applied to the safety mechanism to overcome the biasing force. A biasing mechanism, such as a spring, can be used to apply the required biasing force to the safety mechanism.

Locking mechanism for folding knife

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. The flange coordinates with a shoulder formed on another foldable tool stored in the opposing handle to provide a positive-positional lock for the other foldable tool when the handles are placed in a pressed-together position, increasing the safety and utility of the multi-tool when using foldable tools like a saw or a screwdriver. A clasp augments the positive-positional lock by locking the handles in the pressed-together position, thereby locking the other foldable tool in the open position.
