For a long time I was a strong believer in carrying a real, full size knife on outdoor adventures. For example a Mora kniv, EKA Fällkniv or similar. But when I’ve analyzed what I mostly use a knife for I’ve decided that a small multitool is my way go. I cut string, open plastic packaging, cut a sausage or cheese, file nails, bend stuff with the pliers etc. Only when I go out and need to work with wood to make fire I need a real knife. (But mostly I get along with just breaking twigs and sticks and logs with my hands)
So the Leatherman Squirt has been my friend for a couple of years. I use the knife, plier and file mostly. The small screwdriver has come in handy at some times. The blade is really small but works for cutting string, cheese, salami, climbing rope etc. The second most used thing is the pliers which come in handy to bend stuff or cut thin wire. My absolute favorite thing is that it’s so small you don’t even notice it in your pocket.
