How to use a swiss army knife
A Swiss Army knife can be a useful tool in everyday life, as well as in serious survival situations. Tools come with a wide variety of features, so you’ll need to identify which features are included in the particular razor. Small, compact pocket knives are the ones with the fewest features; Standard Swiss Army Knives have the most features; and lock-blade knives have the most service features.
Use the basic features
Learn to use the main features. There are a wide variety of possible features, but many of them are limited to expensive specialty blades. If you’re going to use a simple standard Swiss Army knife, then you’ll probably only be working with a range of 4-10 basic tools. Most Swiss Army knives include some combination of the following items:
- big leaf and small leaf
- can opener with a 3mm flat head screwdriver
- bottle opener with a 6mm screwdriver, plus wire stripper and bender
- reamer and drill 
- key ring
Use the big sheet. This is the basic component of the Swiss army knife. This blade is usually as long and thick as the handle of the knife. Use it for just about anything that requires a blade. Be sure to exercise safety when handling the razor. Always cut the razor away from the body, and be very careful not to let the blade close on your fingers in the way.
- Cut food, gut a fish, or cut paper. Carve your initials into a tree or carve a piece of wood into another shape. Cut anything that has to be cut
- Use the corkscrew. Some Swiss Army knives include a metal corkscrew for opening wine bottles.  Bend the corkscrew so that it extends directly from the blade, as if the body of the blade were the handle. Use the handle of the knife to twist the corkscrew into the cork, and pull firmly on the handle to remove the cork from the bottle. 
- Be sure to remove the small screwdriver first, if your razor includes this feature. Not all Swiss Army knives come equipped with a small screwdriver.
Open cans with the can opener. This is not a modern can opener, but the old school manual can opener. Place the edge of the can into the lid of the can opener, then press the tip into the inside of the lid of the can until it is punctured. The tip of the can opener doubles as a 3mm flathead screwdriver! 
- You can also use the point of the can opener on the Phillips screws, if you tilt it to use the point instead of the flat width.
Identify the bottle opener. Use it to open the bottles of your favorite drink. The flat tip of the bottle opener also doubles as a 6mm flat head screwdriver. Use it when you need to use something larger than the 3mm can opener screwdriver. 
- Find the wire stripper and bender. This is a small notch at the bottom of the bottle opener.
Sharpen the leaves . The sharpening technique will be slightly different for straight blades and serrated blades. Use the “straight cut” method for the standard Swiss Army knife.
- Straight Cut: Sharpen the blade with a whetstone at a 15-20 degree angle. This will produce a cutting angle of between 30 and 40 degrees. If you are sharpening on a grinding wheel, be sure to quench the metal with plenty of water. This can help prevent high temperatures and blade damage.
- Serrated Cut: Sharpen the blade with a whetstone. Pull it across the flat side of the jagged cut at a 15-20 degree angle.
Identify complex features
Identify what features the knife has. There are many models of Swiss Army knives, each with a unique set of included features. Each knife is designed for a certain type of user, from the casual urban bottle opener to the serious survivalist. Knives fall into several main categories: pocket knives, Swiss knives, and fixed blade knives.
- Some models include: classic, tinker, super tinker, fisherman, camper, hunter, handyman, mechanic, rescue tool, and Swiss champion. They come in categories such as daily, sports and leisure, DIY, LED lights, outdoor, executive, gardening, multi-tool lights, and exploration.
- Read the manual. If you’ve just bought a Swiss Army knife, be sure to read up on the tools that come with that particular model of knife. Read about repairs, maintenance and the correct functions of the tool.
Use a small Victorinox razor. These razors are usually smaller than the standard model and have fewer features. A pocket knife may contain all or some of the following tools:
- Look for the large blade, the nail file with nail cleaner, the scissors, and the key ring. Pull the tweezers and a plastic toothpick from the end of the razor’s handle.
- Find the nail file, the end of which is a flat head screwdriver. Find a bottle opener with the nail file attached. Unfold the Phillips screwdriver, and find the wire stripper.
- Some pocket knives even have a bright LED light, pen, and USB drive.
Explore a complete Swiss Army Knife. This is the type of knife with the most potential features. Some Swiss Army knives come with as few as four tools, while others have as many as 38 unique features. The standard model may contain all or some of the following tools:
- Look for the large and small blade, the corkscrew, the key ring and the can opener. Pull the tweezers and a toothpick from the end of the razor handle. Some knives include more delicate tools such as scissors, a magnifying glass, a sewing eye, a stainless steel pin, and a pressurized ballpoint pen.
- Check for a bottle opener with a screwdriver and wire stripper. Look for the nail file with metal file and nail cleaner. Find the pliers, which usually include wire cutters and a wire crimping tool. Find a paper reamer and a hole punch.
- Find the small flathead screwdriver at the tip of the can opener. Check to see if the blade has a 2.5mm screwdriver, a Phillips screwdriver, and a small screwdriver.
- Some models even have a wood saw, hacksaw, utility hook, or fish scaler with ruler and hook cutler. Find the chisel and scraper. Look for a wrench with a 5mm or 4mm hex drive.
Deploys a pocket knife with a lockable blade. This tool is larger than the standard Swiss Army knife, and the handle is curved for a better grip. Use the lockable blade for more serious cutting, as it locks into place in such a way that you have to disengage the safety to close it. A standard pocket knife bends back at the handle when force is applied to the dull side of the blade. A lockable blade may include the following features:
- Open the large lock sash and feel it stay in place when fully unfolded. Look for a curved, one-handed opening lock blade that has a 2/3 wavy cut. Find the wood saw, hacksaw (with metal file) and scissors. Pull the tongs and toothpick off the end of the handle.
- Look for a 1–2 in (2–5 cm) Phillips screwdriver, a small long Phillips screwdriver, or a small screwdriver. Recognizes the corkscrew, the can opener (whose end is a flathead screwdriver), and the bottle opener (which doubles as a screwdriver and wire stripper). Look for the pliers, with wire cutters and cable crimping tool included.
- Look for emergency features. Lock-blade knives often include a window breaker, seat belt cutter, nylon cable, and a shatterproof glass saw.
- Before bringing a knife to school or a government building, check the appropriate regulations first.
- Many basic Swiss Army knives come with a large blade, small blade, scissors, can opener, toothpick, tweezers, and a nail file.
- Take this outdoor knife with you on hunting trips, camping trips, and fishing trips. It is a survival tool for both urban and wild environments. These knives can also be used for multiple indoor activities.
