A heavy weight model is now available for nail sinkers. It features a head part that creates a sense of unity with softbait while maintaining the conventional multi-stage structure that is easy to pierce and difficult to pull out. The head part comes in contact with the bottom and cover for excellent sensitivity and conveys information to the angler. In addition, the weight can penetrate mat-like dust and vegetation that cover the water surface. It is possible to approach deep ranges and covers that have not been reached before with neko rig.
