Is cavalry suitable for cutting with a knife or stabbing with a sword?

Of course, the sword stab is good. In addition to the speed advantage, cavalry has an impact advantage on infantry. It is obviously easier to take advantage of the horse's own impact advantage with a sword than with a knife. Compared with the power of the horse's own sprint speed, the power of cutting with the arm can be ignored. There is no obvious advantage for a cavalry to stand still and fight infantry. Only by rushing up will there be a great advantage.

Of course, the best stabbing weapon is not a sword, but a spear. The spear can be clipped under the hood, which can give full play to the horse's sprint speed and strength. In ancient times, cavalry spears were almost disposable, and once charged, they would be shortened or abandoned (that is, their hands were empty, and the spears were released when they were inserted into the target, leaving them in the target). Therefore, they are all equipped with sabres for the next charge. This knife is sharp, giving attention to both stabbing and chopping.

It is rare for the cavalry to rush into the infantry phalanx and the infantry to kill each other. Usually they rush into the phalanx, then out of the whole line and then in. Of course, if there is no impact advantage, such as being trapped and not rushing out of the infantry, it will be easier to cut with a sabre.

Using spears is basically a cavalry charge. The cavalry just rushed forward with spears. If there is no target and fighting skills, use the impact of the horse to charge.

In Napoleon's time, cavalry mainly used spears. At that time, cavalry mainly charged in groups, and spears had obvious advantages. Later, because the infantry firepower doubled, the infantry phalanx became a scattered line, and the charge of the cavalry group was tantamount to suicide, so the chances of cavalry fighting alone increased, and it was obviously better to fight alone with a more flexible sword than with a spear. But the cavalry can't give up the advantage of impact, so the sword is better than the knife.
