I've never used a KS so I'm not one to say about its cutting performance. A number of other people here own them, have used them and really like(d) them. But, I'm not going to recommend it or any other carbon steel knife (or even a clad carbon steel knife). Most of the knives the OP identified are extremely stain-resistant. That leads me to believe that he knows he does not want to deal with the day to day care (not maintenance) of a carbon steel knife.
Personally, I don't believe in recommending what I like without knowing what the person wants, whether it's food, wine, knives, cars or anything. What I like can be completely different from what someone else likes. And, because I have no personal experience with the knives he listed, I'm not going to recommend any of those listed. And, I also don't know what he's looking for in a knife. So, I'm not going to recommend anything until I know more and the OP asks.
Also, most of these knives are what I would consider medium thickness knives. They're not thick, but none of these, from what I know, are lasers. I don't recall reading from people much more knowledgeable than me that any of these knives are that thin behind the edge, which is critical in my experience for a good performing knife. But, again, I've never seen or used any of the knives listed.
As for pretty, pretty doesn't necessarily make a good knife. I wish that were the case, but it's not. Don't get me wrong, a lot of people have said the KS is a great cutter. I just don't know.
But, since the OP is in Europe, if he's concerned about shipping, he might want to take a look at Bluewayjapan.
