What the lip does

The lip is not decoration and not a hook guard. It is the one part that turns a plain steady pull of the line into both downward motion and a side-to-side wobble: everything a hardbait does in the water starts on it.

Angle

A plate set almost along the body gives a strong vertical component — the lure runs deep. Set almost across it, it pulls down weakly but throws the body from side to side more sharply. The same body with different lips behaves like two different lures, and that is exactly why one model's line-up often has several versions with different diving depths.

Area and width

A larger area means more drag and a deeper run, a smaller one an easier start to the action at slow speeds. A wide lip rolls the body harder, a narrow one gives a more restrained amplitude at the same depth.

Mounting point

The lip is mounted either low on the head or right in the head itself. The lower it sits, the greater the leverage on the body — so two lures with plates that look identical can dive to different depths.

What it is made of

Most often it is clear polycarbonate: it is rigid and does not go cloudy from scratches right away. A metal lip is rarer and turns up where a narrow, strong plate is needed. The material here is not about looks but about whether the plate keeps its angle after hitting a rock.

A ring on the lip

In some models the tie eye is placed not on the head but on the lip itself. The pull is then applied further from the body, the leverage is different, and the lure runs deeper with the same plate. The knot here needs checking more often: it works under bending stress right at the edge of the plate.

On a pause the lip switches off

The moment motion stops, there is no flow on the plate, and the lure switches to the behaviour of its buoyancy class — it floats up, sinks or holds. The lip does not hold the lure at depth by itself: it only drives it there while there is motion.

Scratches and clarity

A clear plate clouds over time from sand and stones. This does not affect performance: the lip's work comes from its shape and angle, not its clarity — a clouded lip dives the lure just as a new one does.

What happens to it

A lip usually breaks not in the middle but at the point where it is mounted to the body, and most often on a snag. A lure with a crack near the base still works, but the angle already ‘drifts’: diving depth drops off and the action goes uneven. This is checked not by eye but by retrieving it near the bank.
