Buck ops boot knife could be an interesting consideration I haven't seen mentioned. It has a nice serious of carry option, is light and fairly thick. 154cm is nice on the stain resistance scale so it should hold up to a fair amount of sweat. The catch is it has a short handle, 3 finger, and a tanto point. I cut a choil into mine and like it much better, I didn't need that long of a blade for my purposes. Now if the tanto was a little more rounded I thing I would like it more but it does make it work okay as a pry bar if you're into abusing your knives... or the knives you like less.
