Ooh, I will play. Some good models you listed there, some that I have carried for years.
1. Tinker- hands down my favorite and most carried Vic tool since I was about 8 years old. Has a great toolset for the city. I find the small blade surprisingly valuable, and use the back layer philips often. Perfect combo of size, layers, and tools in my opinion.
2. Pioneer- great daily carry knife, excellent toolset, and the durability and aesthetics of the alox scales. I do not own this one, but have gifted several over the years.
3. Farmer- One of my new favorites, and now carry one more often in place of my Tinker. Love the saw, not crazy about the extra layer. Also is usually a backup to a fixed blade outdoors. Have only been wise to this model for a couple of years now, but since I purchased it it has become my most carried model.
4. Cadet- Very versatile daily carry, but not one I own or have ever carried. I much prefer the Tinker to this model and the slightly smaller size is not a big deal to me.
5. Centurion- I do not own this one, but I do love the 111mm knives. I often carry a one hand Trekker outdoors and it serves me well, but it is a sheath knife for me, too big for a pocket. A Vicotrionx that can do some serious cutting. The one hand opening and locking setup are good also. Space on some outings is limited and when I need one knife to do it all the One Hand Trekker is my choice.
6. Super Tinker- Love the Tinker, don't care at all for the scissors on a Victorinox (I know blasphemy) but its true. I even carry the Rally on my keychain in place of a Classic SD, just because I find the scissors a wasted layer. I just plain don't use them and would rather have a saw, file, or small blade. I do understand that they are very popular, and a must have for a lot of Victorinox guys. My wife loves the scissors and won't carry a tool without them.
Just my quick thoughts. Fun post.
