Since I love the manga I created his dragonslayer.
1 - print the blade
2 - print bladecut 1 and bladecut 2 twice and glue them together and then glue them onto the blade
3 - print the handle block and glue that to the blade
4 - print and glue the handle into the blade
5 - print the bottom handle and glue it onto the handle
6 - glue some fabric onto the handle like Guts did *optional
