I was on an FRC robotics team in high school (I just graduated this year). This kind of group naturally generates interesting people, and one of my friends has been doing blacksmithing for several years. He also happens to be a history buff, and so am I. This somehow progressed to use buying some cheap training swords and axes (the dense polypropylene ones) on amazon and organizing Medieval Fight Club on a regular basis. My friend decided that this wasn't good enough and built most of a suit of armor (Breastplate, pauldrons, full helmet, and full cover for his right arm). This wasn't some wimpy LARP armor, he used 16-14 gauge steel with leather padding and tempered the breastplate. Of course we had to test it out, but we only had one set of armor. To make it fair we pitted me and another friend against the guy in armor. I was using a viking style shield I had made, and at one point I rushed at him while trying to block his sword. I completely misjudged the swing and took the full force of the blow to my bare solar plexus (It was the middle of Alabama summer, anyone who has experienced that will understand why I wasn't wearing a shirt). The result was me crawling into a bush while making the kind of sounds associated with strangling murders. Luckily, I was fine after a few minutes of writhing. Somewhere there existed a iPhone video of this, but it cuts off just as I start sucking wind.
