Description
Hammer's improvement "is accomplished by surrounding a cylindrical or crown cutter with a bur or rimmer or crown saw which are placed a short distance in the rear of the cutting edge so that when the thin cylindrical cutting edge is revolving and has entered a short space into the piece of cork it is followed by the bur or saw which removes the surrounding material and enables the smooth edge to penetrate without much friction or binding until it works entirely through and a smooth cylinder of cork is formed suitable for a bottle cork."
