Here is my summary of testing the Killa Zilla.
1. This is a very heavy Khukri, but not any heavier than some traditional ones. Still, in a Khuk with a 12" blade, I'd prefer one around 22 to 28 oz rather than 39 oz. I realize that this is my preference and that some users are fine with the very heavy Khukris.
2. The edge profile on mine was too thick to chop well. Yes, I tried it with the factory edge first. I don't know if all were like this or not. I would prefer the knife be made in 3/16" stock or else 1/4" thick with a full flat grind to lighten the knife and improve the edge geometry.
3. A Resiprene C handle and hidden tang with a traditional khukri shape would be easier on the hand and improve handling. It would also reduce costs some. I realize that Busse Combat no longer uses Res C, so let Scrap Yard sell it!SR77 is fine for this type of knife.
Overall, it is one heck of a chopper and wood splitter. I could live with the handle and even the weight, but the edge profile needs some serious work.
If this is ever released with a thinner blade I'll be ordering one for sure!!!
