To spend $50 bucks on a pair of glorified nail clippers is asinine in my opinion unless you are doing it for the sole purpose of saying, "Look at me! I have $50 nippers!"
Are you going to catch more fish because you ponied up $50 for a pair of nippers? Nope. Does it even make you a better angler in any aspect? Nope.
Let's also look at this from the aspect of do they cut any better than $.39 nail clippers...highly doubt it and let's be realistic here. We aren't cutting 60lb braided line as fly fishermen; we are cutting 2, 4, 6, maybe 15lb mono or flouro. It doesn't take a surgical instrument to accomplish this.
