What is the maximum adjustable 'wrench' dimension Don? That may give a clue as to what it would be cutting.
A Google search of 'copper wire stripper' has a great number of mad scientist solutions. But it seems that the wires would have to be quite a large diameter based on the 'look' of the wrench head adjustment.
Edit: If it were to cut through a cable, the cutting 'blade' as shown appears to be too small. If a cable was 'sheathed' then rotating it would allow one to cut through just the sheathing, remove it and then strip the wires with the roller tool.
