FWIW, I have found that once braid loses whatever coating, that it doesn't snip as well, but if you have a way to put some tension on the line (teeth, whatev), the boomerang works perfectly.

Iv noticed this as well it's older braid it had trouble cutting after its seen some fish and wood and gets faded and frayed a little it has a hard time cutting some times.

Gsx titanium pliers on the boat and kvd split ring pliers on the bank. They have a line cutter and a small plier section plus the split ring tip if you might need it.

Always have a pair of Gerber's in my pocket and another smaller one in my tackle bag. 

I have a pair of needle nose pliers for hook removal, and one of the Mustad KVD line cutter/split ring pliers combo tools for............well cutting line and changing treble hooks. It's all I need. I  must have like 4000 pairs of scissors, but my boat compartments must eat them because I can never find a pair when I need one.
