Yeah i'm a fencer, and here is how they work. Foils and Epees are used as thrusting attacks because they have the sensors in the tips, and Sabres are used for slashing attacks. But i rapier, although it is not used at all in fencing, i think it's a mix of a sabre and a foil, a weapon that is mostly thrust and a little amount of slash, so yah i agree I'm not sure. Does anybody know what a rapier actually is? I only foil, epee and sabre. :P
