A knife includes a handle defining a slot having a first portion and a second portion, a blade coupled to the handle, and a locking assembly configured to secure the blade within the handle. The locking assembly includes a lock button configured to translate between a first position proximate the first portion of the slot and a second position proximate the second portion of the slot, wherein a spindle is configured to translate within the slot, and a spring arm configured to bias the lock button, wherein the spring arm biases the lock button towards the first position while the spindle is within the first portion of the slot and biases the lock button towards the second position while the spindle is within the second portion of the slot.

A knife includes a blade, a handle coupled to the blade, and a clip coupled to the handle at a plurality of attachment interfaces. The clip may be a wire clip which can be difficult to couple to a handle. The coupling at each of the plurality of attachment interfaces includes a through-hole in the handle, a clip hole in the handle intersecting the through-hole, a recessed slot in the handle extending from the clip hole, a clip end of the clip positioned at least partially within the clip hole and extending at least partially into the recessed slot, and a fastener removable positioned within the through-hole. The fastener may be a screw with threads configured to engage both the handle and the clip end to secure the clip to the handle and prevent twisting of the clip relative to the handle.

A knife includes a handle and a blade that is rotatably coupled to the handle. A locking assembly is provided and includes a lock pin, an omega spring, and a transfer bar coupled between the lock pin and the omega spring for biasing the lock pin into a locking position to lock the knife closed or open. The locking assembly may further include a supplemental omega spring on an opposing side of the knife to further assist in biasing the lock pin into the locking position. A torsion bar is also provided within the handle to provide assisted opening functionality. The transfer bar extends at least partially through the handle to locate the omega spring in the handle offset from the torsion bar. The locking assembly assists with holding the blade in the open and closed positions, while the torsion bar aids in assisted opening and closing of the blade.

A locking foldable knife comprises a locking assembly that reliably locks a blade in an extended and folded position. The locking assembly utilizes the surface area of a shaped peripheral edge at a second end of a blade, together with, confirming structures of a locking bar, and one or more stops to reliably lock a blade in an extended position. The locking foldable knife may be doubly secured with a switch lock that prevents inadvertent unlocking.

An auto opening folding knife having a blade pivoted from a closed position to a spring urged release open locked position with a combined self-activating sliding auto release and locking arm. The sliding auto release and locking arm is mounted within the knife handle on dual fixed guide and pivot pins within respective arm openings being spring urged there against. Arm positional projections are engaged on a modified blade shank during operation moving the locking arm back and up then releasing to slide forward locking the blade in auto open use position until manual arm engagement by the user against the arm spring and blade spring for release and transitional closure.

A locking foldable knife includes a locking assembly that reliably locks a blade in an extended position for use. The locking assembly utilizes the surface area of a shaped peripheral edge at a second end of the blade, together with, confirming structures of a locking bar, and one or more stops to reliably lock the blade in the extended position. The locking assembly can also lock the blade in a folded position in one or more configurations of the locking foldable knife.
