My only question is what and or who are you going to use one on?

The police use them on unarmed but aggressive and combative persons. The bad thing about a baton is that they are light and you have to have some decent training to make them effective. The general targets are the hands/ forearms / elbows / legs / knees / shins ect...

Hit someone in the head or neck with one and you might as well shoot them as those targets may be considered using lethal force.

If someone deployed a baton against me I would shoot them.

Something to think about.
