The present disclosure concerns embodiments of a folding knife having a locking mechanism for locking a blade in open and/or closed positions. The locking mechanism a first locking element on the blade and a corresponding second locking element on the handle that is adapted to engage the first locking element when the blade is in open and/or closed positions. The blade can be mounted on a leaf spring in the handle for pivotal movement relative to the handle between the open and closed positions. The leaf spring functions to support the blade and provide a biasing force that resiliently biases in a direction laterally toward the second locking element on the handle.

Folding knife with blade locking mechanism

In certain embodiments of the present disclosure, a folding knife has a biasing mechanism, such as a spring, that applies an opening force to the blade when the blade is in the closed, or folded, position (i.e., the force of the spring creates a moment in the opening direction of the blade). The folding knife includes a latching mechanism that holds the blade in a closed and latched position against the opening force of the spring. To open the blade, manual pressure is applied to the upper edge of the blade (the edge opposite the sharpened edge) to move the blade slightly to a closed and unlatched position to release the blade from being held from the latching mechanism whereupon the blade is then free to pivot under the opening force of the spring.

Folding knife with opening mechanism

In one embodiment, a folding knife comprises a handle portion and first and second nesting blades pivotally coupled to the handle portion for pivoting movement between respective open and closed positions. The second blade in one embodiment is formed with a recess or notch which is sized and shaped to receive the first blade, allowing both blades to pivot within a common plane. The knife can also include a locking mechanism that is operable to retain the blades against pivoting movement when the blades are in their respective open positions. In particular configurations, the locking mechanism comprises a resilient locking arm configured to lock both blades in their open positions or first blade alone in its respective locking position. In certain embodiments, a folding tool comprises plural nesting tool elements other than knife blades.

Folding knife or tool

A folding knife includes a handle portion and a blade pivotally coupled to the handle portion for pivoting movement between an open position and a closed position. The knife can include a locking mechanism that retains the blade against pivoting movement when it is in the open position. In particular embodiments, the blade is coupled to the handle portion such that the application of pressure to the blade in a predetermined direction causes displacement of blade relative to the handle portion in the plane within which the blade pivots. The displacement of the blade relative to the handle portion is effective to release the blade from the locking mechanism and allow the blade to be pivoted to the closed position.
