I think not, like the combo tool on the Victorinox it can only fit Large Flat head screw. I try those hex commonly use on computer, it is a bit too large. The screw driver on the regular can opener of the Victorinox will fit. Then, Wenger doesn't have screw driver on the can opener. What I do on my Wenger Traveler was to file down the finger nail file.
Many of the 2-3 layers Victorinox/Wenger doesn't have sissors or combo tool but scarify the phillips head. So my solution? Carry a Rambler, it has sissors, nail file that can fit common phillips and even better a small phillips on the bottle opener combo tools. When I'm out I need to bring my key so the small SAKs is forever with me.
