A heavyweight model has been released for the Nail Sinker. While maintaining the same multi-stage structure that makes it easy to insert and difficult to remove, the new model features a head that creates a sense of unity with the worm. The head's contact with the bottom or structure provides excellent sensitivity, transmitting information to the angler. Furthermore, its weight allows it to penetrate mats of debris and vegetation that cover the surface of the water. Now, you can approach deep waters and cover that were previously unreachable with a Neko rig.
