I won a set of those floating plastic pliers with tungsten blades for cutting braid, pretty good.
I usually howver use a set of sewing clippers however as they are small easy to handle and cut braid and mono (have no problems with 50lb braid and 60lb mono, haven't tried them on anything heavier). They also only cost $0.99 and are easily sharpened with the ezylap that I also keep in the tackle box to give hooks and knives the once over. I find them better than braid scissors.
