This tip is for when you get your jig hungup either under the boat or out away from you on a limb you can't reach with your rod tip.We take a bass sinker with the brass clip on the top(We like 1/2 oz) take a paper clip (the smaller the better) run it through the eye of the brass clip.When you get your jig hungup you put the paper clip on your line let it fall down the line to your jig shake a couple times retrieve your jig and your jig knocker!!! saves a lot of jigs!!!! carry a couple of these in your pocket.Takes a little time but worth it!!! We show these on our web site easy to make!!!
