There are several groups in the USA that do steel fighting now. We have competed internationally for the past 4 years. I am one of the women fighters, we have been allowed to compete since 2014. The M1 fights are prize pro-fights and the first one that we were involved in was with Sergei Ukolov vs. Craig Michael Ivey, one of our champion fighters. Its a HUGE learning curve over SCA, and many of us started that way. It takes a lot out of you and I promise its the longest 3 minutes of your life lol. If you want to see some of the bigger fights search Battle of the Nations (BOTN) and International Medieval Combat Federation (IMCF). The USA has had teams in both World Championships.
