Victorinox Atlas is a 4-layer 111-mm knife with slide-lock mechanism.
By the way, it seems only slide-locked 111-mm Victorinox knives can be equipped with pliers, am I right?
It’s a very valued (personally for me) model because it was my first Victorinox knife (a long-long time ago when I didn’t collect them as a maniac). I don’t remember exactly what happened with this knife later, it seems it was lost. So, this one was bought “in memory” of my first Victorinox.
Atlas is remarkably like the well-known Outrider model. Looks that Outrider is more useful, because instead of pliers it has more claimed scissors (IMO). Also, Outrider contains another type of Phillips screwdriver.
Another similar model – Carpenter. In comparison with Atlas, it has a back-side Phillips screwdriver (and it’s worse than corkscrew on Atlas). But Carpenter has one, but serious advantage – it is still missing in my collection 🙁
So, if you have a Carpenter model for selling or trade – you know what you should do!
