A lock-blade knife for cooking purposes comprises a housing, a blade pivotally attached to the housing and a locking mechanism. The blade is rotatable relative to the housing between a closed position and a least one cutting position. The locking mechanism is configured to lock the blade in the at least one cutting position. The locking mechanism comprises a biasing member, an engagement structure, and a grasping member. The engagement structure is disposed on the blade, and the grasping member is displaceable from a locking position into a releasing position. The grasping member is biased into the releasing position. The grasping member is in engagement with the engagement structure in the locking position when cutting to lock the blade in position. The blade is rotatable between the cutting position and the closed position when the grasping member is manually displaced into the releasing position.

A self-defense pocket knife with handle of suitable proportion to be grasped in closed fist and a conveyance system configured for the emergency manual conveyance of a blade from a position for storage to a position for use without requiring the user to appreciably alter or compromise grip upon the handle during the course of such conveyance.

Various embodiments of a folding knife are disclosed. In one embodiment, a folding knife is provided that has a handle having a slot having at least one top surface and a blade pivotably connected to the handle, wherein the blade has a tang having a contoured peripheral surface and an open block engagement tang surface, wherein the blade has an axis of rotation. The blade further has a locking block translatable on a plane orthogonal to the axis of rotation of the blade, wherein the locking block has an engagement surface positioned to contact at least one of the contoured peripheral surface and the open block engagement tang surface when the blade is in an open position, and wherein the locking block has at least two bearing surfaces engaging the at least one top surface along two lines.

Provided is a knife, including: blade; a first hilt assembly; a second hilt assembly, the blade being detachably disposed between the first hilt assembly and the second hilt assembly; a connecting portion, disposed on the first hilt assembly; and a handle clip, disposed on the second hilt assembly, wherein a position of the connecting portion is adjustable, such that the connecting portion has a locking position connected to the handle clip and an opening position separated from the handle clip. The knife of the present disclosure solves the problem in the related technology that it is more complicated to disassemble blade of a knife.

A folding knife is described herein. The folding knife includes a release actuator that provides three knife positions: a secured closed position, a secured open position, and an intermediate unsecured position in between the two secured positions, and that opens and closes the folding knife easily and safely. A triple-purpose pivot ring provides an index finger grip, an attachment point, and a pivoting mechanism. The release actuator allows for one-handed operation. A blade holder comprises a blade lock that has two positions, one of which locks the blade into position in the blade holder, while the other position unlocks it. The blade lock may be a push button that unlocks the blade while pressing it down, and that automatically return the lock into its locked position by action of a spring, in particular a leaf spring.

A folding knife with a locking mechanism is provided. The folding knife includes a locking spring that interfaces with a recess in the blade to bias the blade from being pivoted out of the handle. A button interfaces with the locking spring to actuate the locking spring interfacing with the blade.

A bolt action tool is disclosed in accordance with some embodiments. The bolt action tool may include a housing including a housing longitudinal body including a housing longitudinal bore. Further, the housing longitudinal body may include a first housing opening and second housing opening. Further, the housing longitudinal body may include at least one groove. Further, the bolt action tool may include a tool assembly including an assembly longitudinal body configured to be accommodated within the housing longitudinal bore, at least one tool attached to at least one assembly end of the assembly longitudinal body, and a bolt configured to be attached to the assembly longitudinal body. Further, the bolt action tool may include a biasing element cooperatively coupled to each of the tool assembly and the housing configured to maintain the tool assembly in at least one retracted position while the biasing element may be in a resting state.

A utility knife with a locknut includes a case, a blade holder, a blade, a movable pushbutton and a locking device. A blade extension/retraction opening is formed at a front end of the case and provided for the blade to extend or retract, and a movable chute is formed on a side of the case and provided for the movable pushbutton to move. The blade is correspondingly installed in the case by the blade holder, the blade controls its extension and retraction in the blade extension/retraction opening by the movable pushbutton. The locking device includes a locking rod and an adjusting device and uses the adjusting device to adjust the locking rod and lock the blade.

The invention relates to a blade assembly (40) comprising a blade support (14) and a blade (17) that can be detachably fastened in the blade support (14), the blade support (14) having a blade seat (16) having a contact face (42) for a first blade face (43), and a second blade face (44) opposite the first blade face (43) being substantially freely accessible, wherein the blade support (14) has a holder (20) for holding the blade (17) in the blade seat (16), comprising first interlocking formation associated with the blade support (14) and second interlocking formation associated with the blade (17) that interlockingly hold the blade (17) at least in a plane parallel to the contact face (42), the interlocking formation being designed such that the blade (17) has a degree of freedom in at least one direction (v.sub.1) in order to be detached from the blade seat (16).

The special feature consists in that the holder (20) has a latch (30) having at least one bolt that is movable between a bolted position and a released position, engages over a region of the second blade face (44), and locks movement in the direction (v.sub.1) of the degree of freedom.
