Hopefully you already have a tool like the Victorinox Tourist Swiss Army Knife.
I have owned and used one for a LONG time. Its been on many trips with me both in the US and overseas because it is small and useful. In fact, mine is usually in my Camelback so I have it when I go hiking, biking, or camping. I think its a great model that is just the right size for most people. Some multi-tools and Swiss Army Knives are too big and bulky to be of much use, this one however is just right.
There is a downside though. The tools are sometimes hard to open, especially as the tool gets older and the pieces holding it all together get worn. I’ve actually cut myself a few times with this knife because of the way the open/close mechanism works. This has never happened with the Leatherman tools I own, largely because they use a different, more modern design. Its something to be aware of and certainly not a show-stopper though.
In my experience, I mostly use the large blade and the bottle opener. Surprisingly, I have used the toothpick a fair amount too when I am camping. Some of my mountain biking friends carry tweezers in their pockets in case they get stuck with a cactus while riding. Mine has the tweezers built in and fortunately I have never had to us it to pick thorns out of my body. The corkscrew is handy as well, not as good as a real one but when you are on a picnic with your lady it will do just fine.
Very good but not great, yet for around $30 its worth buying because it packs a lot of tools in a sleek package that travels well. Guess that’s why they named it the “Tourist.”
