The rule systems we use include the hitzones for the different weapon categories as well as techniques all participants have to abide to. AFFT mainly uses the young I/CB Hitsystem. Generally speaking, all rule systems are set up like this: The most important thing is it to ensure the safety of the figthing partner as well as one self.
Right after that we try to stay as true to real battles as possible. If a sword hits the enmy with a broad side, it would obviously do as little damage as the body of an axe if the blade misses. Despite hits like this technically counting, we usually don't count them. We are trying to advance our skills after all. Once again we'd like to ensure that you know that this is not about raw power but to control and move the body correctly. Its about the technique, not the strength.
Another important part of the sport is fairness. Since we don't have the control and technical gadgets of fencing as well as no real judges system, honesty and spirit is very important. That means that, if a correct hit has landed, the participant accepts this and ends the battle.
