The first one is a Victorinox with Victoria on the back stamp and measures 91mm, I thought it was a Champion "C" but I cannot find any information on this model also having the Victorionix stamp and also the Victoria stamp on the back side. The second one i think is a Victorinox Director but can't find an example that has the same type of horizonal ribbing on scales. The third a 85mm Wenger i thought was a Swiss Army EvoWood 17 but this one has a Phillips head screw driver not a corkscrew and again couldn't find any other examples that match it. Thanks in advance for any any all help, these can really be a pain to ID with so many different types haha.
