A sheath with modular locking attachments is designed so that it can be secured to the body to prevent the knife and/or sheath from hanging on equipment. The locking attachments secure the sheath to the body and lock the knife in the sheath to prevent an enemy combatant from removing the knife and using it against the knife owner, while allowing the knife owner to easily unlock and deploy the knife when needed.

A guard to protect a user while cutting food (“guard”) has an outer body, a plurality of sides, and at least one grip to securely hold a piece of food within the guard. A plate is secured to the bottom of the outer body to add a further layer of protection. It is preferred that the outer body of the guard is made of a flexible material so that the sides can flex inwardly to accommodate different sizes of food. A method for using the guard to cut food has the food being placed inside the guard, the user gripping the guard and flexing the sides inwardly so that the at least one grip forms a secure connection with the outer surface of the food, and cutting the food such that the plate adds a layer of protection between the cutting instrument and the user.

A sheath has a sheath body having a front plate and a back plate spaced apart from the front plate. The front plate and back plate define a cavity within the sheath body. The cavity is externally accessible through an opening formed between the front plate and the back plate. Snapping fasteners are positioned about a front side and a back side of the back plate. The snapping fasteners each include a male component and a female component. The male component and female component of each fastener are mounted on opposite sides of the back plate. The male component includes a protrusion extending away from the sheath body. The female component defines a recess that is complimentary to the protrusion.

A combination of a sharpening sheath and a knife comprising a blade intended to be stored in the sheath, wherein the sheath comprises a cavity (40) intended to receive the blade and an access opening at one of the ends of the cavity, the sheath comprising, in the lower part thereof, a device for receiving the cutting edge of the blade, characterized in that the sheath comprises, in the upper part thereof, a locking element cooperating with a safety element provided on the back of the blade in order to longitudinally immobilize the knife in the sheath and in that the device for receiving the cutting edge of the blade is borne by an arm rotatably mounted in the sheath, the sheath comprising biasing means acting on the arm to bring the receiving device of the cutting edge of the blade towards the locking element.

A knife and associated guide for the cutting of fibrous batt insulation products, as well as rigid foam board insulation products are described. The knife has a handle and blade, each oriented so as to maximize the ability to pull the blade through the material to be cut, while minimizing the muscular effort and strain required of the user. The guide is configured to easily compress batt insulation products and to be easily moved over the products for improved efficiency.

A pocket knife includes a chassis that defines a cavity and a blade having a cutting edge. 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 chassis defines a base and a sidewall at an obtuse angle to the base. A pocket clip is engaged with the sidewall of the recess.

A film cutter includes: a body unit having a gripping portion, a receiving portion, pivotal portion, a sliding portion, an access slit, and a film feeding opening; a movable knife having a pivotal connection portion pivotally disposed at the pivotal portion, and a cutting portion; an operating unit having a sliding portion disposed at the sliding portion of the body unit, an operating portion for driving the sliding portion, a knife controlling portion for actuating the movable knife to rotate about the pivotal portion and thus allow the cutting portion to be exposed from or to retract into the access slit; two blades disposed in the body unit and each having a sharp edge tilted at an angle relative to and corresponding in position to the film feeding opening; and a guide member mounted on the body unit and corresponding in position to the film feeding opening.
