Katana

There is a VERY big debate on the internet about ninjas and the sword(s) that they used, but I think that that looks like a customised sword that ninja would use. You see, this sword has a wakazashi sized blade, perfect for close-quarters inside houses and castles, and it also has a full length katana hilt, perfect for leverage and disguizing it as just a regular katana. You can do more research on this if you want. Lol, sorry to bother you. It is a very nice picture.
