Ever spent any time on the Spyderco website, Coach? Companies make quality control requirements when licensing out products to manufacturers all the time ... probably every time.
I am not sure I can support your argument here that the Skookum is Kochanski's and not Garcia's design. Certain in fact
You are an accomplished knife-collector, Coach, a connoisseur with your eye in, and a refined sense of your subject of interest. You have, as you say, decades of experience with cutlery and are not afraid to spend on the choicest of items. I get the impression that you could readily identify dozens and dozens of currently available knives that would fit the general outline given by Kochanski. Even starting just with Moras, or any of the hundreds of puukkos out there would give a clue to this.
Aside: the development of the puukko and its variations is an interesting thing to think about here. The Skookum and Woodlore are just two examples among thousands of knives where the authorship of the design itself is of predominating significance. However, the archetypes of the various puukkos you might see, appear to be more happily identified as anonymous, vernacular, folk models that are available for anyone to make (though, presumably, there was a point where someone made the first Tommi some time in the C19th, using a smallish grind wheel). The standards by which these knives are judged are not necessarily their personally authored, unique or singular design, as in the cases of the Woodlore or Skookum. Rather, it is the skill with which they are executed, their recognition and interpretation of paradigm, and attention to the tiny details of local and national (again, anonymous) traditions.
No-one, it seems, can claim authorship of the Tommi. Maybe ‘Scandinavia’ can. It is not possible to steal the pattern of, let’s say, a Hankala Tommi, firstly, because it isn’t his design and, secondly, because either you have Hankala’s technical skills or you don’t: It being the skill of the maker which makes all the difference between one Tommi and another. It might be a different case with his Lastu; which is (like the one Tapio Wirkkala designed in the early 1960s) an identifiable puukko variation that Hankala has branded. Like many cutlers, Hankala both makes his own knives as well as licensing the use of his name and designs to others.
I don’t think that anyone disagrees that the copying of existing knife patterns is a complicated area of regional cultural propriety and law. Like Melton Mowbray pies. And, just maybe, the Woodlore, and copies of it can be viewed as a kind of variation within the folk idiom of the puukko. Though, what exactly one is paying for then, when one lays out £800+ for a ‘real’ Mears Woodlore, is another question altogether – especially when Alan Wood might make you one for a fraction of that price. It is a warm and fuzzy feeling, I guess, which is in no way to be undervalued. Scotch gives you that too. But, let's not get into fake Scotch.
