These electrician/judge cutters are reasonably priced, they are very strong and cut low voltage wire like CAT-5e with no problem. I don't know what max size they will work with but they will certainly work for phone and data cables. My only complaint with these scissors is that the finger holes are a bit small. I don't think I have big fingers but it was a little awkward getting them out of the finger holes. So I changed my workflow to trim, strip and trim everything at the same time and then when everything was ready I started crimping. It's not critical, but it's something to be aware of if you have a lot of work to do or if you're moving from room to room running cables.
