Crankbaits, they get that name because they're floating lures with a diving lip and when they're thrown out on the water they float and they won't do anything until the reel crank is turned. So the crank provides the action. Now to rig one of these, on the bill there's an attachment point. Sometimes there's just one little point to put the line through, sometimes there's a split ring like this one. This one is an older split ring. Just tie your lure right onto that split ring right there with a clench knot or a palomar knot and you're in business. This is also a crankbait. Same thing, it's a long slender lure, got a long bill but it's got that same attachment point, it's got the split ring right there, just tie your line right to that over part of the split ring, cinch that up, throw it out, crank and your fishing away. This is also a crankbait. This is called a rattle trap. You'll notice that this has no diving lip, it's called a lipless vibrator. The attachment point is the same, though. It's right on the top with a split ring attached. Tie your line to the split ring, throw the lure out, crank it fast or slow, depending on the fish's mood and you'll be fishing with a crankbait. It's called a crankbait because once it hits the water it just floats, it just sits there and doesn't do anything until you crank. And that causes it to go down and attract fish.
