lol I've created a jutsu in this exact same motion, a sword of wind but your and mine share 2 major differences, yours is noticeable by the wind distortion and cannot be blocked by physical weaponry. Min on the other hand cannot be seen execpt by the user or doujutsu users and is able to extend like snake sword, also mine can be blocked and parried like a sword as well as defend like a sword, but mine can shattered if hit with enough force yours I'm not so sure
