Black Blade

The Black Blade is a katana like weapon wielded by Black★Rock Shooter.

Background
Black Blade is one of the weapons of choice used by Black★Rock Shooter. However, the only time we see it is in the fight between Black★Rock Shooter and Black★Gold Saw. Black Blade was probably lost in the fight, but whatever the reason, we don't see it again. However, Black Blade was seen again and she uses it to behead both Chariot and the Hooded Figure that seems to resemble Arata. Black Blade maybe used by Black Rock Shooter again to behead other "other selves" as well..

Abillities
It is used like a regular katana. Its attacks aren't much, but it still deals an amount of damage.
