There was one in the old BSP and I found it in the tool pile. It either never worked great or is worn out. I tried it a couple time and it looks like it should do everything. It cuts with a tiny razor blade, and you can set the depth of that blade. Then you can set a roller to the cable diameter. You squish the razor into the cable then and it's supposed to be easy to ring cut or skin the cable.
It always seemed like more trouble than it's worth. The utility knife with a razor hook blade is great.
