Hydro Blade
Overview
The Hydro blade is an experimental weapon idea where a sword with a hollow core is partially filled with water, making a counterweight which moves to the head of the weapon at the strike to deliver more power. An extensive discussion evolved on this subject on the national boards, including the danger of PVC shrapnel. It was eventually concluded that it was utterly useless and didn't help anything at all in any way.
