花剑： 花剑总长110厘米，剑身长90厘米，重量不超过500克，剑身横断面为矩形，护手盘小。比赛采用电动裁判器。剑的末端装有电钮，运动员在比赛中只能刺，不能劈打。当运动员刺出的力量大于500克时，剑头的开关就接通，裁判器上会显示信号。击中有效部位躯干（也就是运动员的金属背心）时裁判器才会显示红或绿色灯，击中无效部位，则显示白灯。每刺中一剑有效部位可得一分。如果运动员相互击中有效部位时，裁判员则判主动进攻的运动员胜一剑。 重剑： 重剑长度与花剑相同，重量770克，剑身横断面为三棱形，护手盘大。比赛采用电动裁判器，运动员在比赛中只能刺，不能劈打，全身都是有效部位（除后脑）。剑尖同样有弹簧头，当运动员击中力量超过750克时，裁判器才会显示彩色灯的信号，得分与花剑相同。但一方运动员击中对方后，另一方再刺中对方，裁判器只显示先刺中一方的灯。如果双方在1/20~1/25秒内同时刺中，则同时亮灯，为互中，各失一剑。 佩剑： 佩剑总长105厘米，剑身长88厘米，重量500克，剑身横断面为梯形，护手盘为月牙盘。剑尖为圆形，没有弹簧头，佩剑即可刺又可劈，这是与花剑、重剑最大的区别。腰部以上包括上肢（除后脑）均为有效部位。每刺中或劈中对方有效部位时裁判器显示彩色灯，而刺、劈中无效部位则无任何信号显示。得分与花剑相同。
花剑是击剑比赛中所用的最轻的武器。剑身为长方形，发起进攻或防御的一方击中对手时便可得分。仅当剑尖触及对方躯干时得分。 佩剑是比花剑稍重的武器，它的剑身呈长方形。佩剑比赛有别于花剑和重剑，它没有关于进攻或反击的规则；当剑身触及对方身体的任何一个部位时，都可得分。不过只有第一次击中才得分。在四百分之一秒内，双方均击中对方，双方都得分。 花剑 重剑 佩剑 横截面形状： 长方形 三棱形 梯形 总长度： 110厘米 110厘米 105厘米 重量： 500克 770克 500克 护手盘： 最小圆形 最大圆形 较大月牙形 是这样
