Well.. I dunno about cleaving guns in half but I do know that a Katana can slice modern day bullets in half. But you would only get three cuts before the thing snaps in half from all the stress. Been proven on myth busters before....

Also I really don't think modern day techniques and technology to make a sword is fair anyway... cuz then yea... any little sword would be effective but master crafted japanese swords tend to do more than western swords... it's just that western swords are more durable. Japanese swords tend to rust easier because of the high carbon steel... high maintenance ya know....
