Abstract: A safety lock for a folding knife comprising a sliding safety button positioned in a slot formed in one side of the knife handle. The button includes a first portion extending outwardly from the handle for manipulation by a user, and a second portion having a beveled surface that is slidingly engageable with a pin protruding from the blade tang. The pin in the blade tang may comprise a pre-existing structure, such as that included in some assisted opening mechanisms, or may be specifically added to the blade tang of a conventional folding knife for the purposes of forming the safety mechanism of the present invention.

Abstract: The present invention provides a scabbard for a combat knife and cutting tool combination. The scabbard generally comprises a body extending along a longitudinal axis between first and second ends, and includes a channel formed therethrough that extends in spaced, parallel to the longitudinal axis, and a cavity that extends along the longitudinal axis. The cutting tool comprises first and second legs pivotally interconnected to one another that extend along longitudinal first and second axes, respectively, with the first leg being removably positionable within the channel of the scabbard, and the second leg being movable relative to the scabbard, but held firmly in position by a releasable strap when the tool is not in use. A combat knife is removably positionable in the cavity of the scabbard.

Abstract: A folding knife having a blade and integral tang pivotally mounted to a handle with a cantilever spring fixedly attached at one end to the handle and extending to a free, terminal end having a lobed portion. A camming member fixed to the tang has a camming surface spaced from the pivot axis extending through the tang. The lobed portion of the spring contacts the camming surface when the blade is in the fully closed position and remains in contact throughout a first portion of the blade movement toward the open position. The spring is out of contact with the camming surface during a second portion of blade movement, from the end of the first portion to the fully open position. Momentum developed by spring force applied to the camming member during the first portion of blade movement is sufficient to move the blade through the second portion of its movement to the fully open position.

Abstract: A folding knife having a locking member which is moved by a plunger and coil spring into a locking position, engaging a shoulder on the tang portion of a blade to prevent pivotal movement of the blade away from the fully open position. The locking member is pivotally mounted at one end in a recess in one of the handle members and extends across the cavity between the members to a manually engageable end in a through opening in the other handle member.

Abstract: Apparatus and method of attaching a threaded member to the proximal end of a knife tang onto which a securing element is mounted for securing handle pieces about the tang. The head of a prior art screw is flattened and laterally expanded within a complimentary shaped notch extending from an open end into the proximal end of the tang with the threaded end of the screw extending rearwardly therefrom. Once laterally expanded within the notch, the screw is substantially permanently engaged therein.
