The bich'hwa, also known as the Scorpion, is an unusual, but extremely deadly weapon used by Blackguards, notably by Karris White Oak, who carries one strapped to her thigh as a concealed weapon.
The bich'hwa consists of a set of iron rings that are placed around the fingers, similar to a knuckleduster, which provides both protection for the fingers, and added weight and hardness for punching. There are a series of forward-curving claws extending from the back of the hand, useful for swiping attacks, similar to a cat's claws. Lastly, there is a dagger extending from the back end, connected to the ring around the pinky, used for stabbing. This dagger portion is often referred to as "the scorpion's tail."
