Next, you need to measure the twister tail against the shaft of the treble to see where you will have to cut the twister tail body to fit it onto the treble shaft. When measuring, be sure that the tail will cleanly trail behind the treble hooks. Now that you have the twister measured, use a household scissors to trim the front of the body of the twister tail. The next step is the tricky part…while holding the twister tail body firmly, insert the treble hook shaft into the twister tail body. You must be careful not to stab yourself with the hooks should your hand slip. A protective glove of some type is recommended until you master the process. The soft plastic will resist being pierced by the blunt treble hook shaft, but it will succumb with steady pressure.
