“The Swiss have an interesting army. Five hundred years without a war. Pretty impressive. Also pretty lucky for them. Ever seen that little Swiss Army knife they have to fight with? Not much of a weapon there. Corkscrews. Bottle openers. ‘Come on, buddy, let’s go. You get past me, the guy in the back of me, he’s got a spoon. Back off, I’ve got the toe clippers right here.'”
I freely admit — I grew up watching MacGyver. And yup, the attitude of putting smarts over brute force — I liked that. Not only was it smart (well, who or what decides whether it is smart ;-)), but it was also more my style. And one thing that really stuck with me was the value of having the right tools available. And in this sense, having a Swiss Army Knife is probably the best tool you can have at your side at almost(*) any time.
Seriously, a good Victorinox Swiss Army Knife provides you with screwdrivers, bottle openers, two blades, scissors, corkscrew, a saw, toothpick, tweezers … and much more. Seinfeld might joke about it, but it’s extremely useful in a lot of situations.
But carrying a Swiss army knife might be a chore, after all, it moves around in your pocket, and if you do not have it immediately available, you might as well not have it available at all (kinda like pepper spray/mace). So, one of the very interesting add-ons is a knife sheath. Personally, I found the Tatonka Tool Pocket, black, S (S = small) very useful. You can wear it horizontally on your belt, which means you hardly notice it. Yet it is there — immediately, without looking or thinking.
Having such a tool — and it is a tool, not a weapon, given that the blade cannot be fixed in an open position — is really helpful. Even if it’s just for everyday tasks like opening envelopes or wine bottles.
(*) Unfortunately, having any kind of knife is prohibited in some buildings and some vehicles, esp. airplanes. Which really sucks, esp. if you want to travel light and have only carry-on baggage — but there you go.
