A knife having a latchless locking mechanism having a handle half with a left handle portion and a right handle portion held apart to form a blade groove. The left handle portion and the right handle portion each include a liner including a pivot slot and a first lock pin disposed between the first left handle portion and the first right handle portion. A blade having a tang that is pivotally and slidably coupled to the handle half with a pivot pin, the tang including a tang slot configured to accept the locking pin and a hook portion extending over the tang slot, the hook portion configured to capture the lock pin when the blade is in a locked position and thereby prevent rotation of the blade from the first locked position to the open position. A latchless locking system is also provided.

A knife includes a blade defining an aperture, a handle pivotably coupled to the blade and selectively repositionable between a first position and a second position relative to the blade, a catch extending between a first catch end and a second catch end, the catch movably coupled to the handle and including a protrusion proximate the first catch end, and a spring coupled to the handle and configured to apply a biasing force on the catch proximate the second catch end. The biasing force biases the protrusion of the catch toward the blade, and the protrusion is received by the aperture to restrict rotation of the handle relative to the blade when the handle is in the first position.

This invention is directed toward a versatile, low profile pocket tool. The pocket tool contains only a single backing plate and can be made without using any screws, pins, or other fasteners. In that way, the implements can easily be removed and interchanged. The stability of the pocket tool is gained by using an tabs that interlock around a track on the implement. This interlocking facilitates rotation and stability. In embodiments, there can be a single tab and a single track, or multiple tabs and multiple tracks.

A folding knife includes a handle, a first liner inside the handle, and a second liner inside the handle and opposed to the first liner. A blade has a tang and a cutting edge, and the tang of the blade pivotally connects the blade between the first and second liners. The blade has a retracted position in which the cutting edge is inside the handle and a deployed position in which the cutting edge is outside the handle. An actuator is at least partially between the first and second liners, and a spring is between the first and second liners and in compression against the actuator so that the spring biases the actuator toward the tang of the blade.

A knife allowing rapid and safe replacement and securement of a blade which can be fixed to a front end of a connecting base of the knife. The connecting base has a rear end that can be connected to a handle, and includes an upper base body, a lower base body, a lock-release member, and a spacer plate that can be located between the upper and lower base bodies and form an engaged-connection groove along with the base bodies therebetween. The engaged-connection groove matches, and enables the insertion therein and engagement therewith, a portion of the blade at or adjacent to the rear end thereof. The lock-release member can be arranged on the connecting base for a user to set the blade into a locked state, in which the blade is securely positioned and cannot be detached, or an unlocked state, in which the blade can be detached.

A hand tool assembly having a foldable implement, such as a blade, and a retractable attachment clip having an actuator is disclosed. A retracting assembly may be coupled to the attachment clip; the hand tool assembly may include a rotatable cam assembly comprising a rotatable cam coupled to a rotatable cam arm having a lifter; the rotatable cam may be coupled to the implement; the rotatable cam may have an off-center rotational axis; when a user rotates the implement, the rotatable cam may also be rotated, causing the position of the lifter to be moved a distance, thereby causing movement of the actuator of the attachment clip thereby actuating movement of the extendable, retractable attachment clip; the foldable hand tool may include a locking assembly having a spine having lug element and a first tooth configured to detachably mate with a first tooth-receiving slot of the implement.

A folding knife that includes a handle rotatably coupled to a blade through a connecting portion of the latter; the blade being adapted to rotate about a rotation axis with respect to the handle between at least a first position, in which it is extracted from the handle, and a second position, in which it is at least partially housed in the handle. Specifically, the folding knife includes a slider element associated with the blade through a connecting element so as to actuate the rotation of the blade, and the handle includes a guide slit formed facing the connecting portion having a shape of an arc of circumference concentric to the rotation axis, wherein the guide slit is adapted to be slidably engaged by the slider element so as to actuate the rotation of the blade between the first position and the second position.
