I agree with TimeTravel_0, buy good cable cutters. They last for decades and do the job right. Shimano's cable cutters have an excellent reputation and the top-o-the-line cutters are Felcos. Expensive but worth it if you work on a lot of bikes.

I have Park's CN-4 cutters and have used them for 15 years but I'm only working on my own and a few friend's bikes. I don't know if they would hold up in daily shop use. The CN-4s work very well on inner wires and shift housing. I prefer good sidecutter pliers for spiral wound brake housing over any make cable cutters.
