In sabre competition, it is the upper body, mask and arms that can hit the effective parts, and the effective parts are all wrapped in metal clothes, which is convenient for judgment. The difference between these three different swordsmanship and competition clothes is also related to the determination of their effective competition parts. The hit part can only be effective if it is sensed by the electric referee. If the tip of the sword does not touch the part covered by metal clothes, it is an invalid attack. Therefore, the metal-clad parts and ranges of the three kinds of fencing clothes will also change because of the different judgment rules of their effective hitting parts.
I think fencing is an elegant and beautiful sport, which has attracted much attention in the Olympic Games. However, fencing is different from ordinary sports, like some ball games, which can be played anytime and anywhere, and requires special venue clothing and equipment, so most people actually stay away from this elegant sport and lack some common sense knowledge.
I feel particularly good in white. We often see fencers on TV, but their clothes are unchanged. In the early days, there was no electronic referee at all, so we came up with a way to put on white clothes, stain the sword head with red ink, and mark it by the marks on the white clothes, so that we can judge the score. So this century-old culture has been passed down.
