Reverse blade katana, also known as sakabato is a katana with the sharp edge inside of the curve, rather than on the outside, which is usually unsharpened. Though there are reports this type of sword was discovered in Japan just recently, it’s believed to be purely fictional katana and there’s no real evidence it was ever used by samurai.
Sakabato comes from the Rurouni Kenshin, a very popular anime and manga series, which is why many people are looking to buy real replicas of reverse-bladed katana.
Reverse blade katana are much harder to purchase however, especially if you’re looking for a fully functional battle ready sword: there are some available by Musashi and Masahiro. If you intend to do any cutting, make sure you get a sword with at least 1050 carbon steel blade.
Could you kindly cite the sources you got that info from regarding the history of the sakabato? I believe, the sakabato is purely a fictional sword, so if you could clarify the authenticity of the information you provided, I’d be very grateful.
It’s a mistake, thanks for pointing it out. I think this article somehow got mixed with double-edged katana or something else. It will be fixed shortly.
Ahhh, I see. Thank you very much for clarifying.
