Spiral Tubing Cutters
A handy tool that costs very little (next to nothing) is a spiral tubing cutter to make polyethylene tubing into a spiral wrap that can be put around wires to hold them in a bundle, or around tubing as an anti-chafe covering. You have to make them, as follows.
To use just start feeding tubing into the hole with a twisting motion, and pulling it out the other side. I have made two of them, one for ¼" and one for 3/8" tubing. The angle of the razor slot establishes the frequency of the spiral cut. You will have to experiment to get what you want. Pictures shown below.
