Video worked at home.
Overall looks cool, but I've seen the same feats done with so many steels. Besides video quality is not the best, I'm not even sure they chopped 10 beams or 1 in 10 places...
Chopping and rope tests depend on the operator skills to great extent, plus knife geometry, weight, edge, etc.
So, I wouldn't base my conclusions about the steel just on that video.
