I needed some wire cutters to trim some thick tensile wires that came with a set of mudguards I was trying to fit. I had been to a couple of cycle shops and they had lent me wire cutters similar to these, but I wanted to get a pair myself as I needed to make further adjustments/trimming.
Although these cutters are designed for brake cable and casing, they also do work on the mudguard wire, though it requires a lot of effort. That said they did the job and I was very happy with these cutters. In terms of cutting through brake cable, they cut it like a knife through butter!
Also found the built in crimper very handy for attaching caps to the ends of the brake cable.
