Looking at the posted pic of the Buck 317, maybe the very subtle dip (or 'clip' ? ) in the blade spine, very near to the rear, is what lends most of the confusion over that one. But it's so subtle, still doesn't look like what I'd view as a clip blade. Still looks too much like the standard 'skinner' in these FH patterns. All of the images I see online of 'Turkish Clip' blades are far more obvious in the deviation of the 'clipped' profile from dead-straight, with the peak of the clip at mid-blade or maybe 2/3rds or so back from the tip.
Edited to add:
Thought I'd seen it before, in a couple of my own knives. Turns out, the same profile is seen in the spine of the secondary blade on Schrade's 25 OT pattern (I have two), with the subtle 'clip' aligned with the plunge grind at the rear of the blade, or just barely forward of that. That being said, online descriptions of that pattern still call it either a 'standard blade' (whatever that means??) or a skinning blade.
