Just go Gardner rig scissors.
Mine are many years old, still working, despite them being used for cutting pike trace wire as well as braid and mono.

For some reason, I seem to recall writing a review on them, and that being displayed on Gardner's web page many moons ago. The pair I reviewed are the same pair I have now, but I have a spare pair, still in the pack for when they do eventually die from abuse.
