The UST 100 Series strips a multitude of cables. Virtually all the blades are interchangeable with the exception of the UST-220. This blade is matched exclusively to the UST-175 handle. Includes Velcro strip for holding back the braided shield of the cable. The UST-150 is designed to strip both RG59/6 (with Cable Stop) and UTP (Unshielded Twisted Pair) cables. Works equally well if you are left handed or right handed. Blades are capable of making over 5,000 cuts.
