IMO, a collapsible baton isn't a horrible choice to carry for self-defense situations if you know how to use them. You must first know the laws in you area of weapon restrictions and use of force. Carrying around any weapon without knowing when and when not to draw them is a recipe for disaster. You must also be trained on how to use the baton so you can use it effectively. A baton offers a wider spectrum of lethal and less than lethal force opposed to a knife. Meaning, a baton can be used for locks, chokes, takedowns and disarms. Either way, be sure to have all the facts and information on baton use before getting one.
