Informative reading. It looks like a very strong package for the price. I checked out the website awhile ago, but many of the blades seemed appearance designed and not overly functional, it is nice to see that wasn't the case for all of them.
Is the edge on the Survival distinct from the main bevel, or does it all just flow together? The handle looks a bit slick, did you have any problems with it moving around? How would you compare it to a standard machete pattern say from Ontario?
In regards to the glancing from the khukuri, this generally indicates the edge is too obtuse, and thus it can't handle the chopping angle (too acute). You can either chop at a more obtuse angle (and lose penetration and increase binding), or alter the edge profile.
