ABSTRACT:
A tube cutter comprises an elongated handle formed in two longitudinal halves and having a C-shaped head at one end also formed into halves and defining an opening through which a tube can be inserted, a C-shaped body rotatably mounted within the two half portions of the head and comprising an opening of substantially the same width as the opening of the C-shaped head, a pawl and ratchet system formed at least between one of the contacting surfaces of the body with a half portion of the head, and a tube cutter assembly mounted on the body and including a tube cutter member mounted on the body, a tube abutment member slidably mounted in the body for radial movement towards and away from the cutter member, and control means mounted on the body to move the abutment member towards the cutter member to press a tube between the two members, such two members having a spacing therebetween in register with the openings of such body and head whereby a tube can be inserted through the registering openings in the body and head and between the two members and the cutter member pressed against the tube and back-and-forth operation of the handle causes rotation of the body and cutter member through the pawl and ratchet system to cut the tube.
