This is the Sakabato, or reverse-edge sword, from the anime/manga series Rurouni Kenshin. It's probably one of the most iconic swords of anime and manga.
I made it as a commission for a friend for his Himura Kenshin cosplay for A-Kon this year. It's made entirely out of various thicknesses of aspen wood. There is also some gold/orange cord for the sageo knot on the sheath; black bias tape for the tsukamaki, handle-wrapping, on the hilt; and some textured paper on the hilt as well. This prop is also able to be fully disassembled, although I didn't give it any seppa. The seppa kind of ruined the sakabato image.
This was also the first time I made a sheath for a full length katana and I am quite proud of it. Although the sageo I put on it I made up completely as I couldn't find any references on how to tie the version in the anime and I wasn't able to figure it out on my own. =/
