As for Wenger vs. Victorinox, they both have some pros and cons. Reminds me of the evergreen Ford vs. Chevy debate. Lots of emotion on occasion; no right answer, debate will go on forever.
Put me in the Vic camp.
As a kid, I was dying for a "Swiss Army Knife" at one point, and someone came back from a trip with one as a gift- a Wenger. A month later, the scales had fallen off from relatively mild drops. I kept the scales, and much later got around to epoxying them back on. The rest of the knife fell apart. I had a second, also a gift, and it eventually fell apart too. They were both SOFT, and didn't hold an edge well at all.
My first Victorinox was a revelation- at that point, I didn't know there were Swiss Army Knives that weren't soft. Only downside to Vics I've ever experienced was the ever-breaking scissor springs, and of course the toothpicks and tweezers going missing.
Now, that was back in the late '60s, so things might well have changed. Haven't needed, or been tempted to try Wengers since, so I don't know.
