Last night, outback, incoming tide (near high). Got a feisty striped bass on a SP minnow. Reached down to remove the hook and she flopped, driving the other treble into my palm. Tried to pull the hook out of my hand first, but fish wouldn't cooperate, so worked the hook out of the fish, revived the fish, and then pulled the hook out of my hand. I had crushed the barbs which made it easier.
So just a reminder: Allows crush the barbs, especially on lures that have multiple hooks. It is nicer to the fish and potentially to the fisherman as well.
