I used to wrap and use a cut off wheel. What a PITA.

Then I picked up a Summit hose cutter. Very simple, takes me about 2 minutes per end.

Many have stated they don't like the Summit fittings. That's all I have on my car. I used their hose and fittings. Theirs are the only fittings that I have been able to take apart and reuse if I cut the hose too long and need to trim more off.
