To put this sword as a beast is mere understatement. Two lucky forum members who fondled it are still recovering from the Gorillaz effect.
It has cleared shrubs, branches with slight wrist-twist and @ 28" as compared to Dan's Waki or the Super Katana, it is surprisingly portable around the trail.

Disclaimer:

The casualty of this video was a dead tree stump, right on a slope. I saw it fit to take it down.
Due to slope as it was on a contour, i had to get proper footing and estimate where to strike.
Yakuzashi took me a while to get used to as i have never wielded a sword. However this will not be the last, as i have hinted at Dr.K :p
You may have observed that upon chopping, i pried the chips out just to test on the flexural strength of the blade.
++:thumbup::thumbup:on the HT, construction and design.
Also worth taken note is that i have not sharpen this sword prior.
In my opinion the dried tree is harder to sink your blade into than a live tree. I have no idea what tree it was but it wasn't too hard compared to tropical hard wood.
The edge has no sign of deformation.

The test was performed without using gloves as i liked the textured feel on hand (paracord wrap).

I would like to thank my cameraman, Simon for filming this (who also survived a falling dead tree) as well Dr. K for making this fantastic blade!

Dan and myself chat on regular basis ;always open for discussion and new ideas, It is always interesting and fun to learn from him.
A low profile person with a lot of intelligence behind that Gorilla logo- his knowledge on HT, steel selection, human ergonomics and the whole package make me a returning customer as well as good friend half across the globe, for sure!
 
Jay, thanks for the review - chop it on! Now find some hardwoods to hack another 129 minutes :D

Wow, Dan's chopper/sword is sure nice and excellent specs.
 
Jay, does the blade have a very shallow hollow grind below the fuller or it that just an optical illusion?
