a cable - stripping tool includes two parts that can be moved linearly in relation to each other , each of the parts including an opening which can accommodate a cable when the openings are in mutual alignment . the first part carries a cutting blade and has a support arrangement with a ring that , when rotated about an axis , adjusts a cutting depth of the blade . a spring element functions to bias the parts in a direction away from each other , while enabling the two tool parts to be brought together against the spring bias by a user squeezing with only one hand so that the cable to be stripped can be inserted into the tool intermediate the two ends to which force is applied .
