+4 on Felco, though I suspect that Knipex could be good too. As to Dremel it yields excess effort per outcome and those outcomes are not consistent.
I have some Knipex pliers and they are very nice. I don't have any Knipex cable cutters so I can't say how well they cut housing. I might grab one and try it, they are a little less expensive than the Felco. I just noticed today my C7 has a nicked blade - looks like someone tried it to cut a bolt with it. Sometimes I hate working in a busy shop....
