I expected a few more votes also. Actually, I probably should have put in a vote for Wenger since the Victorinox Soldier (one of my votes) is nearly the same as the Wenger Standard Issue and I sometimes alternate between the two.
Your comment about the confiscated knives is interesting but it may or may not reflect what people would choose as their favorite - mostly it is just an indication of what they carry. People often buy and use whatever's on sale or more reasonably priced. This may also partially explain the prevalence of the relatively inexpensive 2-layer models.
True, especially people who are not knife people buy a knive that they think can do the job and that is not too expensive. Probably that's also a reason that I find a lot of SAKs in such boxes and never a Fällkniven or Sebenza. And I also realise that those people don't vote on a poll on this forum. It was just something I noted.
