A real Japanese sword, as good as the old ones...

[Aleksey G.]

Oh Man! That just got me, oh it got me good!

I love it, I could not stop laughing, feel bad cause the dude got hurt
but man, oh man .... it got him good.

I see these "practice katanas" at a local fleamarket for $10 USD all day long,
in exactly the same furniture and color wrap as on the video. They are sharp enough to cut the ba**s of a cockroach (really scalpel sharp) but "practical quality" wise in any regard they are absolutely useless.

This video made me think a little: seeing the guy whacking the sword side-wise like that over the table and breaking it easy, of course crappy steel...but do you guys think any of the old blades that are more bridle like lets say maybe indian wootz might break if you hit on side like that?
Does any one have any research on how the old blades mostly break? Is it in direct cut edge to cut edge contact? side hit? or spine to edge?
