Weapon name: Hook Claw (not worthy of a real name)
Description: Like a claw glove, the hook-claw can be worn on one hand. It is not, however, a glove, but rather, the claws are attached to something resembling brass knuckles, which the user wears like normal brass knuckles. To secure the weapon and tie it to the user a bit more, as well as to make it easier for the user to handle, there's also leather straps going from the brass knckles to the users wrists, where they are attached to an armband made out of thick iron.
There are three claws in total, each one stretches about ten inches straight, but instead of staying straight, like normal knives would, they are bended backwards so that they are more like hooks in shape. Still, the low side is sharp and can hurt a lot.
Weapon special abilities: Instead of the normal clawed glove, which acts as an extension to the users arm, this weapon was made mostly to hold the enemy in place. Once the hook is sunk into the flesh, the victim would not be able to pull it out as easily, especially if the user of the weapon doesn't want them to. Struggles usually only widen the wounds and make it even harder to escape. In extreme cases, it can also be used to tear wide wounds, or even tear pieces of flesh out. Still, its hook shape makes this weapon a lot harder to use than normal knives, and so, it's a rather unpopular kind of weapon.
History:
The Hook Claw was invented a long time ago by weapon smiths in East Blue, but was never really popular, since it was hard to handle and could only be used in close range combat. It was, however, utilized by assassins for a while, who would use it for fatal strikes at the enemies throat, mostly severing the arteries and ripping the throat itself out in one move. It was used for executions in the same way, but died out rather quickly. It has been used less and less by assassins and executioners, since it has been deemed too messy, hard to execute, and needed a lot of strenght.
For some time after that, it has been used for duels since it opened flashy ways to unarm an opponent. But even there, it has lost it's popularity. Today, most people have forgotten about it, and it isn't in common use anymore.
