As a visual-oriented visible worm, the curly tail worm is often used in rock fish games. Death Adder Grab 4 ”is a grab worm with an appropriate thick tail. Sometimes it can be used as a visible worm that aims to collect fish on the side that appeals to the eyes without imitating a specific creature, and it has an elongated silhouette as a whole. Since it is a grab, it is suitable for bait fish patterns that flock to all layers such as silver-stripe round herring, anchovy, and small fish of the gobiidae family. Grab is also good at pulling "one step lower range" than the shad tail worm, which has a strong element of kicking back water. The tail keeps fluttering without tearing the water flow that it receives from being entwined with water from beginning to end, enabling a swimming approach with a double effect of visual change and wave motion that is different from the shad tail worm.
