I was invited as a guest competitor in a free style sparring competition hosted by a local sword forum. We agreed that I would only spar in the first division to give the newcomers more chance to win the game. It was the first time I sparred in a competition environment. I had been doing free sparring for very long time, in friendly practice mostly, and on a few occasions doing a duel. However, relying on judges to say what's a valid hit and what's not was a new experience to me. So I have to hit harder and become more obvious in my attacks so that the judges could detect my hits easier. There were six division bouts. They came up with "survival rate" to decide who would proceed to the next divison. I won the division I was in at 76% survival rate, the highest of the day. My opponent's arsenal included Chinese single handed jian, double handed jian, twin katana and a basket-hilt + buckler. It was not the easiest environment for a single longsword to survive.
From the semi-final on to the final bout, it was 1 hit-kill mode where the winner was decided by a single valid hit (disabling / killing). The final fight lasted around 3 mins with both parties, 1 using a single handed Chinese Jian and the other wielding 2 Japanese katateuchi, taking many glancing slices and thrusts without a decisive hit. At last the one with twin swords hit the guy with jian at the head with a killing blow and won the prize.
A student from Australia Stoccata school, Clinton, who studies German longsword under Andrew Brew also got to the semi final with a single longsword against all odds.

After the division sparring, I asked my kendo friend to spar with me, who took up a chinese two handed jian instead of katana. Next, I joined up a queue where I could do some sparring with another esteemed kendoka (the same guy who was wielding twin katana in the division sparring) who was wielding a single katana this time. In these unofficial bouts I switched back to my normal mode because of the lack of need to let judges to acknowledge my hits.
