I have a plug knocker that has a wire frame around the lead weight. And then it's got a long line that attaches to the plug knocker itself. You can attack the wire frame around the fishing line when one of the baits get hung up and then send the plug knocker down the fishing line to knock the treble hooks free from the stumps. We have been using plug knockers for over 40 years. Well since I was just 8 years old and fishing KY lake for lm bass. I saved a lot of balsa wood bombers from being lost to these old KY lake underwater stumps and snags.

Some guys make plug knockers out of used spark plugs.

When you have a line attached to the plug knocker you can pull it up and then let it slide back down the fishing line multiple times until you finally knock the bait free. My commercial plug knocker is very heavy and the heavy wire frame will actually hook onto the treble hooks and help you pull the bait free from the snags.

I have still lost a few plugs when the plug knocker fails to get the crank bait knocked loose but I have not lost very many baits.
