A railroad brake stick head has a head body formed of a lightweight durable material. A railroad brake stick head includes a head body having two opposing planar surfaces spaced apart by at least one sidewall that includes at least one concave sidewall region, wherein the head body is formed of a first material having a first hardness. At least one brace implant is at least partially embedded in at least one concave sidewall region, wherein each brace implant is formed of a second material having a second hardness that is harder than the first hardness. The head body includes at least one implant recess formed into the at least one concave sidewall region, and the at least one brace implant is in the at least one implant recess. Each brace implant can be coupled with the head body, such as by friction fit, adhesive, fastener, or combination thereof.

The invention concerns a gripping handle (1) comprising: a main body (3), a receiving orifice (4) formed within the main body (3) for receiving a sliding removable working bit (2), a blocking lever (14) rotatably mounted on the main body (3) between: a blocking orientation in which it blocks the sliding of the working bit (2), a release orientation in which it enables the sliding of the working bit (2), an elastic pivot (15, 16) designed to bring, by itself, the blocking lever (14) back in the blocking orientation, the gripping handle (1) being characterized in that the main body (3), the blocking lever (14) and the elastic pivot (15, 16) are integral with each other.

Surgical instrumentation.

An apparatus for protecting a tool from an overstrike event. The apparatus generally includes a handle, a tool head, and a collar configuration with two or more collar members adapted to separably surround the handle. The collar portions are affixed to the outer surface of the handle by an adhesive means. The tool head is placed over the handle and collar members and is affixed to the outer surfaces of the collar members with a second adhesive means. The tool head secures the collar members which protect the handle around its circumference in the event of an overstrike event in any direction.
