A versatile hand-held device combining multiple tools into a single unit, often featuring pliers, screwdrivers, knives, and files. These devices are commonly employed by technicians, mechanics, and hobbyists for a wide array of tasks requiring portability and convenience. For example, a technician might use such a device to tighten a loose connection, cut a wire, and file down a rough edge, all without switching between separate tools.
The value of these tools lies in their compact design and ability to perform numerous functions. Their development has evolved from simple folding knives with limited functionality to more complex instruments incorporating a diverse range of capabilities. This evolution reflects a growing demand for tools that can adapt to various needs and situations, saving time and space in professional and personal settings.
