There's absolutely nothing on a Swiss Army Knife that's going to make me want to wait through luggage multiple times for it to arrive. There are travel limitations but not prohibitions on liquids. TSA sized toothpaste is 3.4 oz. I'll live. BTW, an up to date passport is worth it, TSA Pre is worth it and Global Entry is worth it. GE requires an interview but if you live near the office, after you get your appointment, just go to the office on a Sunday and wait through line. I took BART to SFO on a Sunday morning and waited an hour. Done. The California Enhanced Drivers License was much more of an ordeal. If I'm not going through TSA, sure, bring tools. If I'm going light, I pack up an REI Flash 22 day bag ($50) with whatever. A Macbook Air fits in easily. Side pockets for Nalgenes. Ripstop. Light. I can't praise it highly enough. My daily driver is a Timbuk2 Messenger ($80) bag. I think equally highly of it. It is more rugged and so usually the Air lives here. Carryon policy is one bag plus one smaller, personal-type item. These two pass muster. If you must know, yes, I have an American Giant hoodie.
