Those videos were awesome, but I couldn't help but visualize what it must be like trying to explain to security at the airport why he's got a samurai sword, lol.
"Why don't you understand, it's simple, I walk a spintop down the blade of the sword and then balance it on the tip, THAT'S why I carry the samurai sword, geez!"
lol, o.k. probably not like that, but I just like the thought.
