Just attach the split ring of “B tune hook” to the hook eye of the lure! You can blade tune your lure with a simple setting. It changes to a high appeal specification that the hook and blade rotate together. One of the features is that it uses a thick single hook that also supports. The Colorado type blade is a set of silver and gold. Since it is a genuine Hexa B specification, it can be used as a spare hook, or for your jig or minnow. It is also suitable for blade tunes. By attaching it, it acts as a resistance to suppress the movement of the lure, and as a way to further appeal, a new approach expands the possibilities for fish that could not be caught until now.
