The cutters on my Octane line very well... I've never tried to cut wire with them though, just things like zip-ties and plastic strapping, which they work pretty well for. Not really interested in trying them on any real wire because they don't look like they'd hold up very well. I carry my Octane when biking, so I may eventually need to use it to cut a cable or something, but I hope not. I carry it when biking because it's light, not because it's a great tool.
