The Picasso Shakedown Heads use a patent-pending flexible nickel titanium spring (bait keeper) along with a cross-eye Gamakatsu hook to give you the best "shakey style" head on the market. The flexible nickel titanium spring always comes back to position after each fish without breaking.
Because of its elasticity, the spring also allows the entire hook gap to be maintained during hook set. The "give" of the spring allows anglers to lock down and shake their plastics in cover or skip docks without ever losing or tearing the soft plastics. Because of the spring's small size, finesse worms (such as Roboworms or other thin hand poured plastics) can be rigged very straight with no "hump." It also prevents the plastic from tearing.
The Picasso Shakedown heads are coated with the super tough Duraseal process, increasing the sensitivity and allowing them to hold up like no other shakey head on the market.
