Abstract: Shank and knife portions of a cutting tool having particular known utility in the leather tooling art are permitted to swivel within a sleeve member that is held in the chuck of a conventional electrical vibrating tool holder. An angular extension of the shank portion is bevelled to provide the knife portion of the cutting tool for contacting a leather work piece. The ease with which the shank and knife portions of the cutting tool are permitted to swivel is controlled at the time the cutting tool is inserted into the chuck of the tool holder by urging the sleeve against a spring that is coaxially positioned over the shank portion of the cutting tool between the sleeve member and a shoulder that serves to terminate the shank portion.
