I did the same thing a couple of years ago. Long enough ago that I don't remember how I cut it.
It may have been with an angle grinder with a metal cutting blade in it. It still had frayed ends but the hose clams keep them from getting too bad.
I went to the plumbing department and picked up an 1 1/4" tail piece for under sinks. Chrome of course.
I cut to the length I wanted then slit it. With the hose clamp positioned correctly you can hide the whole connection. I was able to spread the chrome piece far enough to get over the hose with the braiding on it. The tension on the cover keeps it in place.
