Hook Swords

Also known as "hook swords" or Tora Fukku Ken (literally " Tiger Hook Sword "), these weapons have a blade similar to that of the jian, though possibly thicker, with a prong or hook (similar to a shepherd's crook) near the tip. Guards are substantial, in the style of butterfly swords. Often used in pairs, the hooks of the weapons may be used to trap or deflect other weapons.

There are five components to the hook sword:

The back, which is 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 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.

Kaito wields a pair of Hook Swords that are made out of silver chakra conducting metal that is stronger than steel and lighter than a feather. Sun and Moon also have many seals on them that can increase there weight for training purposes and if anyone but Kaito tries to use or touch them Sun and Moon will change its weight to roughly 50 tonnes until the offender gives up.
