Braided line brings many advantages, but it also has it's disadvantages. Being able to quickly change lures (without a snap swivel) is difficult because it's impossible to bite through line without causing permanent damage to your teeth - but that's an easy fix!
The slim slot in the seatbelt cutter makes it the perfect tool for cutting any size braided line quick and easy. Just slide the line through the slot and it gets cut without having to open a knife; plus if you lose it, they're cheap to replace!
Some cutters (like the picture) have a whole that makes it attach perfectly to a retractable lanyard or boat. Not to mention, you get 2 for $6.
