The retractable scissors work pretty good for braid. However with all things after a season or 2 they will dull out and once they are dull they just gnaw at it much like nail clips do. I found in the last 2 seasons for trimming my tag ends I just use my fillet knife or I have a box knife I keep in my tackle.
One much like this.
I do alot of Lockport Cat fishing and this knife is not only good for trimming tag ends. But for cutting off the bundles of pickeral rigs you will pull up from the bottom of the red. It also stores extra blades in the handle so a new sharp blade is ready when you are. Again something I have picked up at Princess Auto.
