worm hook/Topwater jerkbait hooks
Topwater jerkbait hooks are similar to worm hooks, but have a wider gap.
This ensures the plastic won't interfere with the hook set, but the shank
and bend also act as a rudder. Some will have a bit of weight on the shank
to boost casting distance and give the bait a rudder for improved action
during twitching retrieves.
