These tools are essential for construction, repair, and maintenance work, allowing users to exert force and precision in their tasks. Unlike power tools, manual tools are often simpler in design and can be more portable and affordable. They require skill and physical effort to use effectively, making them popular among DIY enthusiasts and professionals alike. Proper use and maintenance of manual tools can enhance their longevity and performance.
