切子弹是什么梗

切子弹即用手持的冷兵器（如刀剑等）将射击而来的子弹切开。

因为受的合力方向的原因，被劈开的两半子弹会沿着刀刃的角度向两侧飞出，从而使被射击者免被子弹击中。

要切开高速飞行中的子弹，是相当困难的一件事，需要极高的预判、动态视力、神经反射和身体运动能力，因此相当的帅。

事实上
哪怕是威力在所有枪械里最弱的手枪子弹的动能都相当于强弩（大约750焦耳）。如果是步枪，枪口动能是在1300~3600焦耳，可以轻松穿透2~3毫米的钢板，或是轻易打烂25~30厘米的砖石墙！至于大威力的机关枪、狙击枪什么的就更不要说了…… 事实上有人做过测试，用手枪射击立起来的武士刀，结果是子弹虽然被切成了两半，但是依然在后边的幕把上打出了两个眼。而武士刀本身也受到了相当的损伤……所以该用斧头吗？
