Now you have a portable anchor. When your crankbaits get damaged or punctured. Fill the hole or scratch with polish. Let dry then give two or three more coats to attain a smooth surface. Your bait is back in business.
Safety pins help keep things together.
Slide spare blades, hooks, swivels and the like onto the pin, and snap the pin shut. Now you don't have to worry about them scattering all over your tackle box. Put a drop of hot glue onto the eyelet of your stinger hooks. Slide it onto your spinnerbait, jig or buzzer. You hook will stay in place all day.
