ABSTRACT:
A specialty tool designed for the efficient removal of strips of the outer sheathing (or "wrap") from underground pipe, consisting of a slotted cylindrical steel shaft (10) with female ratchet drive couplings (16) matched into each end, and having cutting discs (14) seated slightly inward from each end. Upon insertion into the slot (12) of a small loosened portion of the wrap and the engagement of the ratchets (18), a strip of wrap is simultaneously cut, pulled loose, and wrapped around the shaft (10) of the tool between the cutting discs (14), as the tool is directed by means of the ratchets (18) around the circumference of the pipe.
