I have a Swiza, basically a Pioneer with a corkscrew. For the most part, it's a nice knife. I bought it earlier this year, wrote it off, and then carried it for a few days recently because it came up in a thread on a multitool related forum I frequent.
I like the blade, which is very thin and hollow ground. It's canted forward, at a more acute angle than any Vic or Wenger I've ever held; I am still not used to it after three days in the pocket. The blade locks in place with a liner lock, which is disengaged with a button, similar to the locks on the 130mm Wengers. Not sure what grade the stainless is, nor have I had to sharpen it yet. Seems to hold a decent edge.
The scales remind me of Wenger's soft touch scales, which I always thought felt weird. I don't have any input on how robust they are compared to cellidor or nylon scales.
The springs on which the blade, awl, and cap lifter lay all have comparable snap to a 91mm Vic. The snap on the can opener and the corkscrew are noticeably weaker, which I don't particularly mind. I may be mixing up the can opener and the cap lifter, though. One was fairly weak, the other was decent.
The drivers seem thin, making me afraid to over torque, and subsequently deform them. The can opener does fit #2 phillips screws, though.
The awl is stubby, but sharp.
The tweezers are as good as anything Leatherman puts out, with slanted tips. Same thin metal you'd expect on a SAK, though.
I haven't opened any wine with the corkscrew, nor have I put in a Vic minidriver, so not sure if one will fit.
Fit and finish seems to be 6-7 out of 10. Personally, overall, I give this knife a 7 out of 10. I certainly like the knife, but like Vics better. Also, Wengers, and even Boker's tech tool (OMG those scales are to die for). More options for just about everything, I guess, which isn't bad thing. But, they're twice the price of a new Tinker or Spartan, for essentially the same tool layout. Hope this helps. I plan on carrying it more often, so will post a longer term carry review at some point in the future.
