Back in the mid 1980's, my UnCivil War reenactment unit participated in a sort of historical faire through the ages. There was a small band of 17th century folks and two of them fought very well with blunted rapiers. Then their leader, who was obviously well trained in that sword, challenged all comers.
I never had any formal sword fencing training and was armed with a Model 1850 Foot Officer's sword, a real one, BTW. I had assembled it from an original late 19th century blade and original sword and scabbard parts. The blade was combat worthy, but I did not sharpen it because I used it in reenactments. I did practice from the sword manual for that sword, though.
I didn't accept the challenge because the guy with the rapier was so good, and my sword was much heavier and a fair bit shorter. Further, he was dressed in period clothing that much better suited to a sword fight.
Finally the lady in charge of Tourism for the city asked me to do it for pictures for the newspaper and tourism. I jokingly asked if she wanted to see me run through, as it would not be a fair contest. Long story short, I agreed to do it for her and the Tourism Board. (She was a good friend to our unit.)
First match, he ran me through in no time flat. Second match, I lasted a bit longer, but still went down fast. Third match, I "cheated" a bit by grabbing his blade in my period leather gauntlet with my left hand and got close enough to hit him in the face with the D Guard of my sword, though I stopped the blow well short of his face. Fourth match, I got a little further away, shrugged my shoulders, moved my sword to my left hand and drew my Colt Navy with my right hand. Then I did a poor imitation of Raiders of the Lost Ark where he shot the guy with the big sword, by cocking and pulling the trigger on the empty revolver. With a 2 to 2 "tie," I decided that was more than enough for me. Grin.
THEN the other guy did a demonstration of using TWO Rapiers, one in each hand, to go up against another guy in his group. I was really impressed.
