This is The Useless Sword. It's like a sword, but useless. So don't use it for fighting because it won't work, just for fun. No supports required. You can print each part with different colours so as to have a better-looking sword. You can also scale as big as you want!
Both parts have to be assembled with pressure and like a puzzle. There is a small piece to level the height of the blade and the handle when assembling (with a hammer).
There is also a file that contains a one-piece blade (print it if you want it to become useful).
