Must say I'm with those who carry a Victorinox. A pocket knife daily carry for me must be reasonably light and not too big. I have the "waiter" model with a large cutting blade, a small screw driver/bottle opener with wire-stripping groove, and the corkscrew. The knife has a toothpick, very indifferent quality pair of tweezers, and a very small eyeglass screwdriver that itself screws into the corkscrew. Won't admit how many TSA now owns as I forget to put them in checked baggage....

Now, when I'm in Africa hunting --- but that's a whole different thread.
