Abstract: Folding knife embodiments are disclosed herein comprising a blade operable to pivot relative to a handle, between an open position and a closed position, about a pivot axis extending through a tang portion of the blade having at least one locking recess. The knife can have a locking mechanism comprising a rod that extends along the pivot axis through the tang portion and a locking member coupled to the rod which engages the at least one locking recess of the tang portion when the blade is in at least one of the open position or the closed position. The knife can further comprise a push button coupled to the rod, wherein depression of the push button is configured to eject the locking member from the locking recess in the blade, thereby unlocking the blade.

Abstract: A folding knife can include a handle portion, a pivot element, a blade, a locking element, a cap, and a rotatable wheel. The handle portion can comprise a first side portion and a second side portion. The blade can pivot about the pivot element between an open position and a closed position. The locking element can prevent disassembly of the first and second side portions when the locking element is in a locked position and allow disassembly of the first and second side portions when the locking element is in an unlocked position. The cap can be coupled to the first side portion adjacent the locking element. The pivot element can extend into the cap. The rotatable wheel can be disposed between the first and second side portions and can rotated to selectively retain the first and second side portions together.

Abstract: An exemplary folding knife has a handle including an inner liner portion and an outer panel. The inner liner portion includes a locking member that is operable to move between an unlocked position and a locked position. The folding knife includes a blade having a tang portion pivotally connected to the handle. The blade is operable to pivot relative to the handle about a pivot axis extending through the tang portion between a closed position and an open position. The tang portion engages the locking member when the blade is in the open position and the locking member is in the locked position. The folding knife also includes a lever member pivotally mounted to the locking member. The lever member is operable to block the locking member from moving from the locked position to the unlocked position when the blade is open.

Abstract: Folding knife embodiments are disclosed herein comprising a blade operable to pivot relative to a handle, between an open position and a closed position, a blade-locking mechanism disposed in the handle and being moveable in a first direction between an unlocked position and a locked position to retain the blade in at least one of the open or closed positions. The folding knife may further comprise a safety mechanism mounted on the blade-locking mechanism and being moveable relative thereto in a second direction between a release position and a safety position. Wherein when the safety mechanism is in the safety position, the safety mechanism and the blade-locking mechanism are blocked from moving in the first direction, and wherein when the safety mechanism is in the release position, the safety mechanism and the blade-locking mechanism can be moved in the first direction to move the blade-locking mechanism to the unlocked position.

Abstract: The present invention relates to embodiments of a folding knife having a seat belt cutter on the blade tang. In one embodiment, a folding knife comprises a handle and a knife blade. The knife blade comprises a tang pivotably connected to the handle, and the blade is operable to pivot relative to the handle about a pivot axis extending through the tang between a closed position and an open position. The tang comprises an enlarged tang portion that extends outwardly from the handle when the blade is in the closed position, and the enlarged tang portion comprises a cutting portion.

Abstract: Disclosed herein is a folding tool having a handle, a tool element and a ball bearing assembly. In some embodiments of the present disclosure, the handle of the folding tool includes a first, second side panel and a first, second side panel liner wherein the ball bearing assembly is positioned between the first side panel liner and the second side panel liner. The ball bearing assembly includes a first bearing race and a second bearing race each race having a ball housing. A plurality of balls reside partially within each ball housing and are positioned to contact an adjacent side surface of the tang of the tool element thereby allowing the plurality of balls to roll along opposing sides of the tang as the tool element is pivoted from the open position to the closed position. In some embodiments, the tool element is a knife blade.

Abstract: 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.

Abstract: The present application concerns embodiments of a folding knife. In one representative embodiment, a folding knife comprises a handle comprising an inner liner portion and an outer panel, the inner liner portion including a locking member that is operable to move between an unlocked position and a locked position. The folding knife further comprises a blade having a tang portion pivotally connected to the handle, the blade being operable to pivot relative to the handle about a pivot axis extending through the tang portion between a closed position and an open position. The tang portion can be configured to engage the locking member when the blade is in the open position and the locking member is in the locked position.

Abstract: A lifting mechanism or locking mechanism includes a housing, an axle attached to the housing, and an element including a cam surface mounted for rotation on the axle. The distance between the cam surface and the housing changes between a maximum clearance distance and a minimum clearance distance as the element rotates about the axle. The lifting mechanism also includes a line which can be moved between a first position over the cam surface and a second position.

Abstract: 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.
