I already mentioned them a few weeks ago, but Gladiatores are worth more than one look. They're a group of german enthousiasts who train with real swords, and try to recreate the dueling techniques of the middle ages and renaissance. And they're *%#&@* impressive.
If you ever thought only the Japanese had intricate fighting technique, look and think again. You might even want to role play a cavalier swordsmaster or swashbuckler after you've seen these.
