the metals used in a (real) katana are WAY harder than any kind of jacket you'll find on a bullet. if it was a "soft" round (non-jacketed) round, then this is more of an exercise in physics and theater than anything else cold steel makes a sub-quenched "working" katana and samurai blade that will cut half way through a steel garbage can, and mantain a good edge afterward.
Is that a Hatori Hanso Sword? :naughty: There is a similar video on Nasioc with a Guy like an M-16 or something bigger shooting at a katana. It took about 6 shots before the Katana actually broke. I will look for the link once Nasioc comes back up. Ok, not a weak ass M-16. .50 Cal Machine Gun vs Katana. http://youtube.com/w/Swords-vs.-Guns-pt.2?v=Hvu2Nc9Wwhw
