A hand tool is a device that is operated by hand rather than powered by electricity or batteries. Common examples include hammers, screwdrivers, pliers, and wrenches. These tools are designed to help with various tasks such as construction, repair, and crafting, making them essential for both professionals and DIY enthusiasts. Hand tools are typically made from materials like metal, plastic, or wood, and they come in various shapes and sizes to suit different functions. Unlike power tools, they require manual effort, which can provide greater control and precision in tasks. Proper use and maintenance of hand tools can enhance their longevity and effectiveness.
