Easy hook removal
One of the first things that I noticed when I started fishing was that some fish really swallow the hook. Fish can be very eager to take the bait, especially if you've got the right fly or bait on the hook. It can be a little difficult to unhook a wriggling fish and the last thing anyone wants it to harm a fish unnecessarily. This is why I always pinch the barb on my hooks, no matter what type of fishing I'm doing. It really makes hook removal easy and I can often return a fish undamaged and sometimes untouched.
