Birkiland – Umbuster
This design from Birkiland merges two important functions into one simple package. You can keep yourself completely dry from rain while punching someone with a dibilitating blow to the face with this invention.
I really don’t see myself ever using this invention except maybe in a rough and rainy London Neighborhood? A bit too James Bond-ish for my personal tastes, but I’m always wooed by the product mashup.
