I dunno man...I did kendo for a little bit a few years back. The reflexes and speed of some of those dudes are off the charts. Search kendo and youtube and watch the all-japan finals in highschool or college or just the reg all japan finals if you can find them. I'm gonna say that this is legit. I don't think cutting through a steel pipe is too easy either!
True, I've studied documentaries of buddhist monks and their ways, know most of this is actually possible.
Just think it's strange he doesn't cut the bullet or the veggies in the studio, just a small pipe.
With proper equipment, cutting through a pipe is not THAT big of a deal.
That, combined with the bullet cutting (had to be set up perfectly and required lot's of luck, took a LOOOT of tries) makes me call BS.
Still impressed though, watched it all the way through actually.
