ABSTRACT:
A cutter for a helically corrugated tube in which a pair of rings are connected by a blade carrier to form a track around the tube. Each of the rings comprises a pair of "C" members hingedly connected at one end and releasably connectable at the other end to form the ring. Each "C" member has a pair of rails supporting a circumferentially movable carrier having rollers at each end engaging the rails of the adjacent pair of rings. A holder on the carrier projects outwardly between the rails. A yoke in the holder carries the cutting blade; a compression spring in the holder drives the yoke and blade toward the tube. A threaded cup on the holder adjusts the compression spring and also provides a handle recess.
