Ironbloodblade

A week ago I got an idea while playing some games and watching some anime. Maybe somebody can guess from where I got my inspiration from.

The base concept are weapons made from blood but how can it be realized?
My thought process looked like this: "Blood contains some iron, iron is magnetic, maybe a magnetic field can form a blade? ".
The problem was, that the amount of iron in human blood is too small. So I thought about a solution.
The answer was easy, add more iron to the blade. I decided to make an iron sand cartridge which is connected to the handle of the sword.
This sand mixes with the blood from a vial and a magnetic field (created by magic or technology) forms the blade.

In terms of design I chose to let it look like something self made. The handle is made of brass tubes and brass screw nuts. Same as the cartridge and the vial.
