i stand by my statement lmao it's borderline stupid to use mana ACTIVELY just to have a standard sword. it sounds cool in paper but it's actually stupid in reality considering if that's the case, he could have just have a blunt sword with maintenance-proof function so it doesn't need a scabbard for ease of transportation and quality of life functionality(since you don't need to maintain your sword at all) and just use mana to NOT ONLY make the sword have edge but the edge itself is so sharp that it could rival obsidian stone knife sharpness test
also he didn't say that he could use mana to reverse the edge of the reverse sword.
