The handiest thing in the world - a cable splicer's kit - consists of a pair of electrician's scissors and a sheepsfoot knife in a handy belt pouch (around $25 at Home Depot's electrical dept).
I've used those snips to cut a million things in the course of my work day, including the top of my finger almost completely off.
Home Depot carries Kleins, but good quality scissors are also made by Jensen and Jameson.
