OK, when we first looked at this product, we thought "Why would anyone want to pay for that" ? Certainly with our years of experience with CAT5 we would not need a tool that seemed so foolish. Then we tried it. We were wrong. We couldn't believe how well this product works !! This economical CAT5 and CAT 5e cable jacket stripper has been specifically designed to strip the cable jacket from Category 5 and Category 5e cables. Will NOT nick the inner conductors. Just place the spring loaded stripper around the cable and spin with your index finger a few times. Then flex the cable and the jacket pops off. Makes your cables look very professional, especially inside an RJ-45 Connector. Every professional needs one of these in their toolbox.
