I didn't know they made these for so long that they could be so different.
Not seeing the screw diff?
The saws used to have angled teeth - then the teeth were made perpindicular, still exactly the same distance apart.
So did the Woodsman (Huntsman with phillips instead of corkscrew) used to be called the Artisan? Or does the No Bail make it an Artisan? I have a couple of Huntsmen, with bail, scraper arc on caplifter, Victoria stamp, and one has the older angled saw teeth and the other the perpendicular teeth like today. Otherwise identical knives - except the angled-tooth one has a thicker main blade. They both have the scissors between the blades and the saw (long nail file on the back). So the saw change occurred -- after 1951's new can opener, after the hidden rivets of 1961, before the lanyard ring replaces the bail around 1968...
