This invention is about a fish fillet knife sheath with sharpening function, inside the sheath body features a storage chute, inside the storage chute features a sliding in sharpening rod, a pop-up pressure spring located between the front end of the storage chute and the sharpening rod, in the rear of the sheath body features a locking lever with a hinge, the rear part of the locking lever features a locking block which extrudes towards the sharpening rod, the front lateral side of the locking block features a locking slope oblique towards the sharpening rod from the front to the back; the rear part of the sharpening rod features a compaction slope which is coordinated with the locking slope, the sheath body features a cam switch via the switch pin with a hinge, the cam switch features a locking pressure spring. This invention is simple, convenient, beautiful and hands protective.

The present invention relates to a knife cleaning device with a body that is primarily comprised of a top surface and a generally parallel bottom surface, a pair of generally parallel side surfaces, wherein at least one side surface of the pair has at least one handle assembly, a generally parallel front surface and rear surface and an interior cavity. The front surface and rear surface are each further comprised of a generally rectangular opening, connected by the interior cavity that receives a blade of a knife. The device can be applied to the blade of the knife and pushed to the rear of the knife, wherein the device can be slid forward along the blade using the handle assembly to dislodge the food from the blade.

A knife includes a blade having a first side face and a second side face. The blade includes zirconia as a main component, and includes a cutting region including at least a ridge portion between the first side face and the second side face. When a portion including the cutting region in the first side face is referred to as a first cutting face, and a portion including the cutting region in the second side face is referred to as a second cutting face, the proportion of cubic crystals of zirconia in the first cutting face is larger than the proportion of cubic crystals of zirconia in the second cutting face.

The disclosure is the only product of its kind that has the capability of eliminating all of the friction during a bow drill set-up when attempting to start a fire and offers a multi-purpose tool that can be used to benefit all individuals during various occasions. This avant-garde product is uniquely designed with a sharp twenty Skandi grind knife, single bevel, and a bore that is easily accessible from either side of the handle. Moreover, the Byrd fire starter is crafted with durable materials to ensure long term sustainability and can be easily transported and stored in any casing and/or bag during expeditions.

A cutting implement handle that is configured to provide a user with an improved grip so as to facilitate a stronger engagement with a cutting implement. The cutting implement handle includes a body wherein the body includes a first side and a second side along with a top edge and a bottom edge. The body has formed on the second side a thumb engagement indentation that is angled towards the first end and configured to releasably secure a thumb. A plurality of phalangeal notches are formed on the bottom edge. One of the phalangeal notches is formed to engage a portion of the index finger of a user and includes an upper segment having a surface that is formed to progress inwards to the centerline of the body. An upper phalangeal groove is also present in the top edge and has a tapered surface.

A tool having a detectable wireless marker or tag is provided. The tool has a working portion with a projection or tang by which the working portion of the tool is held, a wireless tag located on, but insulated from the tang, and a handle disposed over and encompassing the projection or tang and the wireless tag. In an exemplary embodiment, the wireless tag is insulated from the tang using a housing assembly made up of: an enclosure with a side opening for receiving a detectable wireless tag; a cover that securely fits over the side opening; and a snap-fit assembly component integrally formed on an outer surface of the enclosure for receiving a tools' tang. The invention allows for the use of fragile markers or tags, which are protected by the housing assembly from temperatures and pressures used during, for example, tool handle manufacturing processes. Also provided is a method for providing a tool with a detectable wireless tag, and a method for tracking and tracing tools used within a packaging facility.
