The engraving at the base of the main blade with this string of characters indicates an old souvenir model. Current products have the exact same functions, shape, and size, but are renamed "Excelsior." This is a thin 84mm model, making it easy to handle even for beginners. Its main functions include a main blade, a mini blade, and a key ring. The main blade, in particular, can be used for a wide range of purposes, such as cutting food, cutting tape, and opening packages. This model is also known for being a favorite of Junko Tabei, the first Japanese woman to summit Mount Everest. It's a practical tool that also performs well in outdoor settings like mountain climbing.
