I lost my veteran old Champion knife the other day and as I check around for something to replace it, I found this. It is the model s557 which has the pliers and the inline Phillips screwdriver. It is a slightly smaller knife in length with crafted scales on it to conform to your hands. It is made by Victorinox with some of the components of Wenger. The knife has a fixed main blade which is a few millimeters shorter than the standard blade in the Champion. It has a slightly smaller pair of scissors which have a spring loaded metal support to hold them open. Much better than the spring. Two things I don't like about the scissors is that they have a restrictor to keep em from opening too far. and they are sort of sarrated so you aren't going to sharpen them easily. The pliers are held open by the same ridged mechanism. They have two fulcrum points. One to close them completely. One to cock them open for small nuts etc. I don't see a really practical reason for this, they are so small. I used to use pliers as super tweezers and the ones in the Champion were micro-speck. You could pull a leg off a fly with them or a splinter out of your palm.. With the ones on the Evolution -- don't think so- not so exact. Now this knife has a locking blade. I like that. The lock mechanism in my opinion was way to hulking big. So I filed it down some. It is also not in the way and now does not even get caught in my pocket seam when I retrieve it. All the other blades are the same as on the Champion.All and all I like the knife. The slightly smaller size is okay. The tool is pretty well thought out. I still might go the extra 24 bucks and get an other Champion but I like this. Guess I have to keep it now that I filled on it.Edit on 6/28/2018: I have to ad this to the review. After trying to use this knife for a while I have found it's scissors to be absolutely worthless they don't open up enough to work with. I went ahead and bought a Swiss Champion to replace it.
