i am not in a position to get one of these, but i can offer a bit on the design;
the handle curves remind me of an old axe handle that i have (no longer attached to an axe, it came with an antique axe and was all rotted around the eye) that has the most beautiful contours. i couldn't bring myself to throw it away. it has become my pattern. anways, the contours have a way of locking the hand in very solidly and preventing any slide whatsoever, a very secure grip. i think the handle is likely very solid and comfortable in the hand, based on the drawings.
i personally prefer the profile of #1, as it looks sturdier for chopping, without as much chance for tip failure. personally i would spend more time chopping saplings to make some weirs to catch fish in than chasing around boars in a survival situation, and i don't do any hunting outside of survival, so i don't need a finer point for peircing. also, the blade would probably balance a little bit more tip forward, to help in chopping.
i have never used a ring knife like this, but it seems like it would be a good way to choke up on the blade without worrying about slipping up onto the edge.
about the swedge, it seems like a swedge really needs to be all-or-nothing for function. if it is halfway, with some of the spine remaining, i don't see much increase in penetration ability over no swedge, but it will help your baton bite the dust a little faster than a plain spine. on the other hand, if the swedge is done all the way, there is quite a bit of increase in penetration, and will be nearly useless with a baton. in the middle seems like it more cosmetic than anything to me.
