Bob Dozier rarely makes his D2 knives thicker than 1/8" and many just as long. Most moras are thinner than 1/8", including ones in this length. 1/8" is quite thick and will handle everything but heavy lateral prying, particularly in D2 which is a brittle steel to begin with. The Survive! Knives GSO-4.1 is only 5/32" thick and of similar size with a skeletonized handle:
M390 model, easy prying:

CPM-3V model, heavy prying:

Keep in mind that the spine thickness is for lateral strength. If you need more, get more. The skeletonized handle will be full-thickness so may actually have more support than the blade - i.e. if prying with this knife, it is more likely to break in the blade than the skeletonized handle. But this knife (KOA model V) is NOT designed for hard use - it uses brittle steel with good edge-retention in a very light-weight design. They even provide the hardness and edge geometry! It isn't a knife I am interested in, and the spine is too straight, but otherwise the design looks good to me!
EDIT: Regarding the serrations, they don't look deep enough to me but may function perfectly well for their intended use, which is NOT wood-carving, paper-slicing, or skinning. Serrations, when well done, are exceptional for cutting rope, vines, webbing, animal hide, meat, bread, even cardboard. I am a fan of serrations :thumbup: in their proper use.
