Abstract: A pocket knife includes a chassis and an insert engaged with the chassis, wherein the insert defines an insert surface. A blade has a retracted position in which the blade is inside of the chassis and a deployed position in which at least a portion of the blade is outside of the chassis. An actuator is slidingly engaged with the chassis to reposition the blade between the retracted and deployed positions. A lock is pivotally connected to the chassis and engaged with the blade in the deployed position to lock the blade in the deployed position. A stop pin is connected to the blade, and an end of the stop pin extends a predetermined distance from the blade to engage with the insert surface when the blade is in the deployed position to prevent movement of the blade with respect to the chassis.

Abstract: A fixed blade knife includes a first scale having a first scale inner surface and a second scale opposed to the first scale having a second scale inner surface. A blade has a cutting edge that extends from the first and second scales and a tang that extends between the first scale inner surface and the second scale inner surface. A first recess in the first scale inner surface extends from the first scale inner surface partially through the first scale, and a first flange is around at least a portion of the first recess in the first scale inner surface. A first boss extends from the tang of the blade into the first recess in the first scale inner surface, and a perimeter of the first boss increases away from the tang of the blade.

Abstract: A pocket knife includes a chassis and a blade having a retracted position in which the blade is locked inside of the chassis and a deployed position in which at least a portion of the blade is locked outside of the chassis. An actuator is slidingly engaged with the chassis to reposition the blade between the retracted and deployed positions. A lock is pivotally connected to the chassis and has a surface defined by the lock. A first projection extending from the surface of the lock engages with the blade in the deployed position to lock the blade in the deployed position.

Abstract: A pocket knife includes a chassis that defines a cavity. A blade having a cutting edge has a retracted position and a deployed position. A slider inside the cavity has a first surface opposed to a second surface. A front operator is inside the cavity, and the slider engages with the front operator to move the blade to the deployed position. A rear operator is inside the cavity, and the slider engages with the rear operator to move the blade to the retracted position. A spring connects the front operator to the rear operator along the first surface of the slider. A longitudinal recess is defined in the chassis. A first boss extends radially from at least one of the front operator or the rear operator and slidingly engages with the longitudinal recess in the chassis.

Abstract: A pocket knife includes a chassis and a blade having a retracted position in which the blade is inside the chassis and a deployed position in which at least a portion of the blade is outside of the chassis. A tang of the blade has first and second legs that extend from the tang to define a recess in the tang between the first and second legs. At least a portion of the chassis extends into the recess in the tang between the first and second legs when the blade is in the retracted position.

Abstract: A pocket knife includes a first scale having a first scale inner surface, a second scale opposed to the first scale having a second scale inner surface, and a cavity between the first scale inner surface and the second scale inner surface. A blade has a cutting edge, and the blade has a retracted position in which the cutting edge is inside of the cavity and a deployed position in which the cutting edge is outside of the cavity. A recess in the first scale inner surface extends from the first scale inner surface partially through the first scale, and a flange is around at least a portion of the recess in the first scale inner surface. A boss extends from the second scale inner surface into the recess in the first scale inner surface, and an end of the boss is tapered toward the second scale inner surface.

Abstract: A folding knife includes first and second scales and a blade having a tang and a cutting edge. The tang pivotally connects the blade between the first and second scales. The blade has a retracted position with the cutting edge between the first and second scales and a deployed position with the cutting edge outside the first and second scales. An actuator between the first and second scales has a first position that locks the blade in the deployed position and a second position that allows movement of the blade between the deployed and retracted positions. A spring is in compression with the actuator between the first and second scales so that the spring biases the actuator toward the tang of the blade. A detent in the actuator engages with the tang when the actuator is in the first position and the blade is in the deployed position.
