Kill la Kill - Dual wielding sewing needles.

Next thing you know, everyone will triple-wield with a blade in their mouth and be female Zoros.

Each sword sprouts arms and picks up two more swords, which then sprout arms and pick up two more swords, so that each person is wielding seven swords in each hand, and each one capable of swinging independently. There will be sword fights within sword fights within sword fights within sword fights until only one warrior and one sword remain. And it will be glorious.
