A knife, components thereof, a sheath therefor, and associated methods. The sheath may be releasably retainable on the blade by engagement of connection structure of the sheath and blade formed by inserting the blade into the sheath. The blade may include a bottle opener. The knife may include a finger recess adapted to receive a finger of a user when the knife is gripped by the user. The knife may be an ulu knife.

Provided is a knife facilitating haft replacement to suit a person's preference and purpose of use. On the front side of a tang 3 extending in the front-rear direction, a protrusion portion 7 capable of biting into a haft 50 made of, for example, a wooden rod such as a tree branch is provided so as to be separated from the tang 3 and protrude to the rear side of the tang 3. A first receiving portion 8 receiving the haft 50 with the protrusion portion 7 biting into the haft 50 is provided on the rear side of the tang 3. The end surface of one end portion of the haft 50 is bitten by being pushed in from the protruding end side of the protrusion portion 7 toward the front side of the tang 3. With the protrusion portion 7 biting into the haft 50, the other end portion side of the haft 50 extending to the rear side of the tang 3 is received by the first receiving portion 8. As a result, the haft 50 is attached to a knife 1. As a result, a structure for connecting the tang to the haft 50 is unnecessary and a person can easily replace the haft 50 to suit his or her preference and purpose of use.

A utility knife includes a body having a front end and a rear end opposite the front end. A blade holder, supported by the body, is moveable relative to the body, to move a blade between an extended position and a retracted position. The blade extends through a blade aperture when in the extended position. The blade aperture is sized to receive a hook attached to the blade of a tape measure.

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 inner holder, an outer holder, and the detectable wireless tag positioned between the inner and outer holders. 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.

A knife includes a single flat right triangle like steel blade with a pointed apex and sharp-edged sides with an apex height shorter than the length of its base. The knife also includes an elongated handle integral with the blade and formed along a hand wide hypothenuse base. The handle has two spaced apart finger openings in the handle, one adapted to allow a user's little finger and ring finger to pass through the finger opening and the other adapted to allow a user's middle finger and index finger to pass through the finger opening. The apex of the blade is adapted to be positioned over the middle finger of the user.

An antimicrobial and adhesion-proof titanium tableware and a manufacturing method of the same are provided. The antimicrobial and adhesion-proof titanium tableware is made of a titanium substrate, and includes a contact portion and an oxidation layer structure. The contact portion is used for contacting foods, food ingredients, drinking water, beverages, or body parts of a user. The oxidation layer structure is formed on one part of a surface of the titanium substrate corresponding to the contact portion. The titanium substrate is made of titanium in α phase, and the oxidation layer structure is a titanium dioxide film in a rutile crystalline form. The oxidation layer structure has a roughened surface and an oxygen diffusion layer formed at an interface of the oxidation layer structure and the titanium substrate.

A combat vehicle rescue tool for operating a combat lock to open a door of a combat vehicle by engaging an exterior mechanical rescue coupler includes a handle having a first end extending in to a first forked arm and a second forked arm. A selectable angle end wrench includes a box wrench which is sized to fit an exterior mechanical rescue coupler of a combat vehicle door. A rectangular stem of the end wrench has at least three angled faces on a rectangular stem end opposite to the box wrench. A detent mechanism engages each of the at least three angle faces and the pair of face surfaces to set a predetermined angle of the selectable angle end wrench with respect to a long axis of the handle. A spare fastener pin can be threadingly stored in the end face of the tapered end of the tool.
