"She Mao 蛇矛" is literally translated as "snake-spear". The reason why 'snake' was used is because the weapon has many curls that are shaped like a snake.
However, I don't much details about its history, can someone please elaborate or do some research?
From what I've heard, the weapon didn't exist in the historic 3 Kingdoms time, and came into use probably around the Song or Ming.
I think the reason for the wavy pattern is that it easily lacerates flesh. A single slash from such a weapon would be like being cut with many blades, as the wavy edge moves up and down flesh.
That could also increase it's armor penetrating powers since when you swing a concentrated part of the edge would contact armor.
I am only guessing this from what I've heard about European flamberge swords though (those greatswords with a wavy pattern)
