IMHO compound grinds area just a latest fad like ex: American "tactical" tanto's, "Rambo" hollow handle survival knives, etc :thumbdn:
As a rule, majority of these designs are poorly designed/made and are terrible for actual use. Obviously, there are few well made exceptions that actually perform very well, ex: single piece milled out hollow handle knife, etc.
In the OP example of tool that is trying to be "jack of all trades, but master of none"! It would be poor performer as either dedicated "fighter or survival" knife!
I can see how compound grind could be possibly useful on 7"+ medium to large fixed blade knife to be used solely in the woods, if the design is done right, possibly compound grind on CS Kukri!
BUT it is totally useless on 3"-4" folder to be used 99% of the time in the city!!!!!!

It's too short to take advantage of either grind, you can't chop with it or slice!:thumbdn: If you need pry bar than sharpened screw driver would be better choice, than small folder!
PS SAK's are OK BUT not the best knives, because of non-locking blades which are not safe and handle is not very ergonomically comfortable to me, I prefer my Leatherman Wave with locking blades/saw and better handle. After couple of my SAK's had scales break apart or fall off, I no longer use them.
Both of them I think off as multi-tools rather than knives, if I need to cut something I reach for actual knives BM, ZT etc. When somebody asks me how many knives do I carry on me, I don't include multi-tools in that count! Very rarely, when I don't have on me my EDC would I use multi-tools knife blade for cutting.
