1. Different people: Foil is the most basic and difficult sword. Beginners, experts and other experts of all ages will use this weapon. Epee is the slowest sword, so there are many elderly people, and getting range and defense is a test of physical fitness, and there are many athletes; Sabre is the fastest sword, and the competition is very explosive, mostly young men.
2, the effective area is different: the foil is all the trunk from the neck to the lower abdomen, and only the button that stimulates the tip of the sword can be scored; Epee is a button including a mask and shoes, and only by "stabbing" the tip of the sword can you score; Sabre is the trunk from the mask to the lower abdomen, excluding the lower abdomen, plus the upper limbs but excluding the hands, which can be scored by stabbing.
3, the rules are different: foil has the concept of priority, whoever attacks first will have priority, if blocked, it will lose priority and cannot score at the same time; Epee has no priority, whoever hits it scores, so they can score at the same time, and the game may be tied; Sabre has the concept of priority and cannot score at the same time.
