In fact, many martial arts include the use of weaponries; it's not just about relying on the fists alone.
After all, these forms of martial arts were originally devised for genuine life-and-death struggles, where in the face of armed opponents, the physical body naturally falls short.
The creators and proponents of martial arts often used weaponries as well.
Some even say that martial arts evolved from weapon skills.
But no matter which theory one subscribes to, it represents one fact: martial arts and weapons are inseparable.
The form of Bajiquan that Wang Sheng practiced naturally included weaponries, with a variety of them at that—sabers, spears, swords, staffs, and other types of weaponries included.
However, no matter which weapon skill he trained in, it would certainly match the fighting techniques of Bajiquan. After all, using weaponries was meant to strengthen one's own martial art, not to limit or discard what one was best at.
