"Spike head" is a tube jig head that makes the irregular and low trajectory escape action unique to tube jig heads that induce reaction bites more reliable. The shape with spike-shaped protrusions on the tip of the head holds the tube worm firmly from the inside, preventing even the tube worm with a thick head from cracking and popping out of the jig head. Also, if you set it to a tube ringer equipped with a weed guard function, it will play an active role as a tube jig head that can aim tight at obstacles.
