Using the Leatherman MUT is a breeze. For one - hand operation, just use your thumb to open the tools you need, leaving your other hand free to hold something else. When you need a specific bit, you can easily access it from the handle storage. To replace parts like the pocket clip or the carbon scraper, use a Torx #8 screwdriver.
Here are some important things to keep in mind. When using the wire cutters, make sure the wire is within the recommended thickness range to avoid damaging the cutters. And when using the knife, always be careful and keep your fingers away from the blade.
For maintenance, after each use, wipe the tool with a dry cloth to remove any dirt or debris. If it gets wet, dry it thoroughly to prevent rust. Periodically, lubricate the moving parts with a light oil to keep them working smoothly. Also, check the bits and replace them if they start to wear out.
