Describe a tool or piece of equipment that you find useful

A tool that I find very useful is a small multi-purpose knife that I always carry in my bag. It's the kind that has a blade, scissors, a bottle opener, a screwdriver and a few other little tools, all folded into a red plastic case about the size of my finger.

I was given it by my uncle on my fourteenth birthday, and I've had it for about seven years. At first, I used it mostly on camping trips for cutting rope, opening cans and preparing food. But now I use it on a regular basis, almost every day, for all sorts of small jobs. For example, I use the scissors to open packages, the screwdriver to tighten the screws on my glasses and the little knife to peel fruit. Last month, it even helped me repair my friend's laptop bag when the zip got stuck, and everyone was impressed.

I find it useful for several reasons. Firstly, it's extremely convenient. Instead of carrying several tools, I only need one, and it takes up almost no space. Secondly, it's reliable. After years of use, the blade is still sharp, and nothing has broken. Thirdly, it has made me more independent, since I can solve minor problems on my own and don't have to wait for someone to help. There are many moments when people say, I wish I had a screwdriver, and I can take mine out. It sounds like a small thing, but I really think it is one of the most practical objects I own. When I travel, I make sure to pack it in my checked luggage, of course, and not in my hand baggage.
