A power operated rotary knife including an annular rotary knife blade supported for rotation in a blade housing. The rotary knife blade including a body and a blade section extending from the body. The body includes an outer wall including an arcuate surface having an upper region extending from a first upper end portion to a second intermediate portion and a lower region extending from the second intermediate portion to a third lower end portion. A plurality of gear teeth extend downwardly from the upper end of the body, each of the plurality of gear teeth including an outer peripheral face forming a portion of the upper region of the arcuate surface of the outer wall. The body outer wall includes a bearing surface having a lower bearing face in the lower region of the arcuate surface and an upper hearing face in the upper region of the arcuate surface.

The invention relates to a tool for manual or especially automatic removal of tenderloins from half-carcasses of slaughtered animals. The tool comprises a circular knife blade, a blade housing supporting the knife blade, and a movable knife blade protector. The tool is connected to a motor capable of driving the knife blade. A tenderloin is partly cut free with the knife, the knife blade protector is activated to protect the knife blade and the tool is used to pull the tenderloin free from the half-carcass without damaging the tenderloin with the knife. The tool can be arranged on a robot and can be used for automatic removal of tenderloins from half-carcasses at slaughterhouses.

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 near the tang, and a handle disposed over and encompassing the tang and the tag. In one embodiment, an article is formed onto the tang. The article includes a side opening in the form of a downwardly sloped slot sized to securely anchor and partially encompass the tag, which extends above and beyond the tang contained within the article. The invention allows for the use of fragile tags, which are protected by the inventive article 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 field dressing apparatus includes an elongated handle. The handle includes a first end and a second end. The apparatus also includes a head member. The head member includes an at least generally planar, at least substantially smooth first surface. The head member further includes an at least substantially smooth second surface cresting apart from the first surface. The head member further includes an at least substantially smooth tip extending between the first surface and the second surface. The apparatus also includes a blade fixedly attached to and extending between the second end of the handle and the first surface of the head member. The blade includes a blade edge. The blade edge and the first surface of the head member together form a notch in front of the blade edge.

A cam plate for a cam mechanism of a hand-held, power operated rotary knife. The cam plate includes a cam member engaging a split blade housing of the power operated rotary knife and being operable to change a configuration of the split blade housing between a first, blade-supporting state and a second, blade-changing state. The cam plate includes a cam cover for maintaining engagement of the cam member with the split blade housing. The cam cover includes first and second lateral sides. The cam plate further includes a depth limiter having a support portion and a working portion. A lower or carcass-contacting surface of the working portion The support portion includes first and second sections extending from respective opposite ones of the first and second lateral sides of the cam cover. The working portion includes an arcuate section, a lower surface of the working portion being spaced below a lower surface of the cam cover.
