While SwissTool scissors are better than Wenger's, I still don't want them on the 91mm and 93mm knives. For EDC, the normal scissors are in a different league.
I get what you're saying, but I think we're looking at things from very different points of view. For me, I want the best functioning scissors for most EDC tasks. I'm not thinking about my knives in a hundred years.
You, on the other hand, collect vintage knives and value their robustness. The scissors you prefer will definitely last longer than the ones I like, but what's the point of having them if they can't be used?
I've seen Swiza's scissors in pictures, but I've never used them. They look better for cutting paper or sheets in general, but again, they wouldn't work for me. I use the scissors on my SAK to cut my fingernails, for example. None of the other ones can do that.
Standard Victorinox scissors are irreplaceable.
