x3,719 for boomerang tool.  Love that thing.  

I have 2 boomerangs but after the first day of use they fail to stay in the closed position and catch on my shirt since I wear them on a lanyard.  I sprayed oil in one since it was used while wading. Oiling it caused it to never go into the closed position again.  I use a William Joseph nipper made for fly fishing.  Fly fishing tools seem more rugged and refined.

Just kidding, I use a small pair of scissors. I never can seem to find my knife when I need it, so I carry scissors in my backpack.

For braid I found these small scissors at the dollar store.  Works awesome, as for other line I'll use nail clippers or the scissors.

I got some scissors with some Sufix braid. They work well for me.

Cabelas cheap braided scissors work great for me. They are small enough to fit in my shirt pocket and the tips are rounded

I use a crimper for cutting heavy mono and wire line. Recently bought a kvd split ring plier that works well for lighter line.

Grey Spyderco Delica 4 Full Flat Grind, Japanese VG-10 steel.    And of course a Leatherman Wave or Surge.

I used the Mustang KVD braid cutter this past year and it did an alright job for fluoro and braid. It would be nicer if it was stainless so it didn't rust but for $7 it's not too bad.

That's what I use too, plus it's nice that it has a set of split ring pliers built in. I also keep a pair of kids scissors on the boat, as well as some needle nose pliers with a wire cutter, in-case I have to cut a hook or something.

The cutters on my H2O 7.5" Forza aluminum pliers cuts any line, including braid, better than anything I've ever used.
