Abstract: A method and apparatus for tightening band-type clamps in a desired tension is provided. The device includes operating handles for compact and one-handed operation. A pinching roller provides tensioning by means of a first handle. A second handle accomplishes bending or locking and cut-off without the necessity for rotating the tool as a whole. The tensioning handle folds tightly against or into the body when the desired tension is attained, providing a signal that the desired tension has been attained. The tool is foldable to a compact storage configuration and provides for reversal of a cutting device to provide a new cutting edge when the old cutting edge becomes worn.
