No matter where you travel to and why you are traveling there, we strongly suggest you consider taking a Swiss multi-function army knife. Known for years for its practicality, the knife helps travelers open up devices or screw or unscrew anything. You don’t need to be MacGyver to use the device. These device’s easy tools can help in instances in which you need to change batteries in an electrical device found in hotels in Hawaii or South Beach vacation rentals.
