Tinker. Phillips head is a must have.
To me, a corkscrew on a pocketknife is as useless as SOS mode is on an EDC. If I carry wine out in the field it is in a skin or flask anyway, at home I use a real corkscrew/cork lifter that works better.
TCW60: That knife on top looks great, I love the nice saw blade. Do you know which model it is?
