Hand tools are tools used only by hand
Hand tools also include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives. Garden forks, pruning shears, and rakes are examples of hand tools used outdoors. Portable power tools are not the same as hand tools. Humans have been using hand tools since the Stone Age, when stones were employed for pounding and cutting. Tools were manufactured during the Bronze Age by casting copper and tin alloys. Bronze tools were sharper and tougher than stone ones. Iron supplanted bronze during the Iron Age, and tools grew even stronger and more lasting.
