ABSTRACT:
An improved casing for a flexible metal drive shaft or cable of the type used for transmitting power from an electric drive motor to the handpiece of a meat trimming knife. The drive shaft is rotatably mounted within the bore of a cylindrical sleeve formed of a dielectric plastic providing a low friction surface for the inner rotating metal shaft. A metal wire braid is formed about the outer surface of the plastic sleeve to increase the longitudinal stability of the casing. An outer covering of a plastic material, preferably a food grade PVC, covers the wire braid.
