Operation:

1. Grasp the tool in the area of the window cut, applying forefinger pressure on the cable against the blade. (Fig.1)

2. Draw the tool in the direction of the desired window holding pressure against the cable. (Fig.2)

3. To terminate the window cut, lift the back end of the tool until the window chip breaks off (Fig.3)

4. The low profile design also allows for tool operation on a face mounted cable. (Fig.4)
