I jam the toothpick into the bullet sinker..from the base end...and snap the toothpick off.this is called 'Pegging it' it keeps the bullet sinker from sliding up and down the fishing line..

ALSO , you can slide the bullet sinker up about 18inches.. the sinker will stay..as you drift a long..you are now fishing a modified Carolina RIg..most of the time I don't use a bullet sinker..I pinch a round split shot near the eye of the hook..to texas Rig..or slide the BB shot up to Carolina rig...The BB shot gives your worm a much more realistic presentation ..diving slowly..

Also..note the paperclip in the hook and sinker box..when you remove the bullet sinker ...you will been to push the p[aper clip into the hole to push the wood out so you can use it again.
