Blade
One of the most functional parts of a standard Swiss Army knife is the blade. The blade has many uses, from cutting food, rope and clothing, to being used for self-defense. Though small, the blade has a sharp edge and should be handled with caution. When not using the blade, it is important to tuck it back into the main part of the Swiss Army Knife to prevent accidental injury.
Nail File and Screwdriver
Whether you need to even out a broken nail on-the-go or tighten up a loose screw, the nail file part of the Swiss Army knife will come in handy. The rugged surface has a sandpaper-like texture that will smooth jagged nails, and the tip of this attachment functions as a flat head screwdriver. It fits neatly into the head of a small screw to loosen or tighten it.
Scissors
One of the most useful attachments on the Swiss Army Knife is the miniature pair of scissors. Though tiny, the scissors of the Swiss Army Knife function to trim loose hairs or strings and open up letters or packages while on the road. Some may feel limited by the small size, but the scissor attachment of the Swiss Army Knife is safer to travel with than a full-size knife.
Keyring
The classic model of the Swiss Army Knife has a small keyring at the end so that it can be attached to you keys for easy access. Attaching your Swiss Army Knife to your key chain will make the small device easier to find in a large bag. The key chain function also makes it easier to remember to bring your Swiss Army knife when traveling, since it is attached to something without which most individuals rarely leave home.
