Mensur, as far as I know, is still practiced in Germany. The neck is tightly wrapped in layers of silk, the eyes and nose protected by iron goggles, and the hands with heavy gloves. The participants face each other inside a circle, out of which you cannot step. There is little footwork, since the idea is to BE cut. The "winner" is the first person to make a bloody cut more than an inch long.

I've got a great scar on my outside of my right leg from where a guy (accidentally) cut me with a corn knife (small machete) when I was about 13. And another in my right eyebrow from where my mother dropped me on my head. These are plenty; I don't feel the need to participate in mensur.
