I still am of the mind that it is not a very good idea to carry/use any item from any catalogue that labels it as a "self defense" item. Special pens or weird shaped plastic items that have no real world function, is a lawsuit waiting to happen. If you are attacked, and you use some pointy self defense pen, or shaped piec of plastic stick made to inflict harm, it won't matter that the cops won't charge you. Even if you walk out of the police station with the cops patting you on the back telling you what a good job you did on the lowlife, it's just begining. I'm sure soon as a screaming liberal lawyer consults with the perps family, they'll have 10 people swearing he was a good boy, member of the church choir when he was young, and the pillar of his family. A wrongfull death/injury suit will take what you've saved for old age, and you'll get off lucky if they don't garnish your wages till hell freezes over. What is that dedicated kubton going to do that the butt end of a AA minimag not going to do? Or for that reason, a normal sharpy or Zebra 701 pen sold at Walmart? Surviving the assault is only one part of it, surviving the aftermath without being a long term contributor of some lowlifes now life of leasure, is the bigger part of it. Take out somebodys eye or do some brain damage by hitting him in the temple accidently while thrashing around striking at him, and even some deputy to the deputy D.A. a few years out of law school, will have little trouble painting you as some sort of concrete comando. Learn to use normal everyday items that can't be proven to have any conection to any self defense catalogue or mall ninja outlet. That elderly lady who fought off an assailent in a church with a ball point pen, just used what she already had in her hand. The plain old Bic stick worked fine for her, left her assailants face kind of pockmarked. Made it easy to I.D. him. There was no repercussions for her. Kubotons, jaw jackers, weird shaped micarta or plastic items with no function, self defense pens that look like they were made for a weapon, are a bad idea in the long run.
