Is there a double edge Katana?
Excuse me, but I'm curious about something I've heard mentioned in the realm of swords and weaponry. Is there truly a concept of a "double edge Katana"? As far as my understanding goes, the traditional Katana, a Japanese long sword, is renowned for its single, curved edge designed for precision cutting. So, I'm intrigued to know if there's a variant or a misconception surrounding the existence of a double-edged version of this iconic blade. Could you please clarify if such a Katana truly exists, and if so, what are its distinguishing features and potential uses?
