High leverage diagonal wire cutters will work. Not the 6" long variety, they'll crush down on the cable and ruin it. 8-9" long Channellocks is what I have and snaps cable and housing cleanly.
Klein, Channellock, high leverage cable cutters also are good, with curved blades for a clean cut.
A small wire rope cutter is about the same price, and made for the job. Some for $20 instead of top of the line for $60.
