Very good, too many here give opinions of knives based on pictures.
But consider this, the collective value hasn't come for the Wirkkala puukko by accident or by designer's reputation. All of it's aspects are well thought out, the looks excellent and frankly counting out the design (the looks) aspect is strange. We as knife enthiusiast now don't really care what a knife looks like? I see, hmm....
...And absolute handle ergos? No ,not the best. Thats individual preference but I certainly would never declare something as nothing special by my personal ergonomic needs. Should it have the best ergos to count as an exceptional knife? I guess with that said we don't have too many good knives around. How do you feel about the blade profile or the grind? Something wrong there? How would you describe the blade in general?
I try not to give opinions that aren't based on real experience. In my opinion, to do so would be rather dishonest -at least if one doesn't mention that the opinion is based on just looking at a picture or something like that.
I can't speak for anyone but myself, and I for one do not consider looks to be anywhere near as important as performance and ergonomics. As for knife enthusiasts as a group, I cannot and will not speak for them. I'm just one guy, and when you talk to me, you get my opinions, not the opinions of knife enthusiasts as a group.
As for the qualities of the Wirkkala puukko, I will say this. If you ask me, for something to be called exceptional, it must be exceptional - that is to say, superior, unusually excellent. It's all well and good if a knife has good ergos and a working geometry. But does that make it exceptional, or just good? My answer is the latter. Exceptional is not the same as good. Good is good. Exceptional is much better than good. The Wirkkala is good. But it isn't exceptional to me. The exceptional thing about the Wirkkala design is 1) looks and 2) rarity. That's about it. And since I do not particularly value either, the knife becomes less than exceptional to me. That's how this stuff works.
Let me put it this way. In your opinion, what makes the Wirkkala exceptional? How does it perform in an exceptional fashion, that is to say, how is it superior in performance to other good puukkos? I've thought long and hard about that one, but I just can't find anything that would make me say it performs exceptionally. It's good. But that's all.
