Razors are tools for cutting hair close to the skin, with designs that range from simple blades to powered shaving devices. Manual razors use an exposed or guarded blade: straight razors have a folding handle and a blade that opens for use, while safety razors position the blade behind a protective guard. Electric shavers use powered cutters, often beneath a perforated foil or behind rotating heads, and some electric models also serve as clippers for trimming hair. The collection includes examples of blades, straight razors, and electric shavers, connecting traditional manual shaving tools with modern powered alternatives.
