Abstract
A coating material such a TiN, Ti(CN), or (TiAl)N is deposited onto the blade edge region of a steel knife blade blank by a cathodic arc process using linear deposition sources with simultaneous heating and rotation of the blade blank relative to the deposition sources. The blade edge region may be sharpened or unsharpened prior to deposition of the coating material. If the blade edge region is unsharpened prior to deposition, it is thereafter sharpened, preferably on one side only.
