Well, you know what they say about opinions, my friend... I certainly agree the original Wirkkala puukko is a collector piece. I agree it's a deserved one, since it's relatively rare and easy to identify. But even so, I do not see it as anything that is functionally special and therefore worth paying a lot of money for - unless you just want to have it for your collection, which is of course your prerogative. That in itself, though, doesn't make it an exceptional knife in terms of performance.
I find the handle to be nothing special in use, and while the geometry has nothing wrong with it, I don't find it particularly worthy of special applause that could not be granted to other well-made puukkos. As for the sheath, it certainly works and is traditional, but it's even less special than the knife itself.
I don't see myself belittling Wirkkala as a person. I'm merely saying I find the puukko he designed to be nothing special in terms of performance, ergonomics or indeed anything except physical appearance. It looks special, that's for sure, but that's about it, in my experience. Looks mostly do not interest me in knives, so in that sense it's no surprise that I find the design less impressive.
Now, I'm not saying it's bad. I'm just saying it isn't amazing, certainly not as amazing as many rate it to be.
