The hook sword, twin hooks, fu tao, hu tou gou (tiger head hook) or shuang gou is a Chinese weapon traditionally associated with northern styles of Chinese martial arts and Wushu weapons routines, but now often practiced by southern styles as well.
There are five components to the hook sword:
The back, which is often used as a regular sword.
The hook, which is used to trip enemies, catch weapons and for slashing.
The end of the hilt, which is sharpened.
The crescent guard, which is used for blocking, trapping and slashing.
The link, which is used when using a pair. The two hooks can loosely connect, and the wielder swings one hook sword, in a way that the second is extended further out, almost six feet. While the second is in the air, the dagger upon the hilt slashes the target. In this way, the wielder can extend their reach out from three feet to six.
