Buck 301 or 303, both are some real tough stockmen, and full stainless. Three springs, thick blades, no in between liners, bolsters are part of the scale liners, stainless pins, and strong materials for scales, they sport a very tough construction, and seem to be able to handle quite a lot.
The blades are not pinchable, but far from nail brakers.
The serpentine jack from queen, recommended above, is indeed a fine knife, though i had mine reprofiled to more of a slicer type. The steel will take a patina though, definitely not as easy as Case CV, but still. Not exactly stainless, is close, but the edge holding is outstanding, and the D2 resists abrasion very well, good thing if you cut a lot of cardboard

The main blade is pinchable, and again, this one is not a nailbraker as well.
Anyway, the stockman is a great choice, if you don't have one by now, maybe is time

You sure have plenty to choose from...
