Uses of serrations can be depend on the situation and application. I'll be honest, my gerber prodigy out-performed any other knife I've battoned with, and I always battoned
with the serrated edge. It may have been the blade geometry at that point, maybe it allowed it to slide through more easily. But as far as serrations go, they're a pain in the rump to hone. But, then, if you need to notch something or shear through roots or vines,
the serrations are useful. (Well, your seal pup elite has a rasped spine..that can notch.)
I have wysteria growing everywhere here..and it's strong enough to hold my weight up..I've actually dulled several fine-edge knives on it, but serrations cut through it easily.
To me, in my opinion, a half-serrated edge has the best of both worlds--you've got fine edge for incising, whittling, shaving, but the serrated for tearing, shearing, and even sawing. Just a pain in the butt to hone. Ugh.
Oh, before I forget--again, I want to thank you for sharing those pictures. I had reservations about that knife, and after looking at your pictures several times, I've decided that a small knife that the one you've shown would be more effective for my needs than a big ol' clunker of a chopper. (I wouldn't be surprised if that's saved me from injuring myself with a bigger, clumsy knife.) That sheath is beautiful, btw, very nice. Oh, also, in case you're wondering, the Sog Seal Pup Elite, from what I have seen,
seems to have a pretty considerable tang for a hidden-tang knife--I've gotten a close look at the tang on them. Thanks again.
