Handsaw Safety Background A handsaw is a tool used in woodworking and carpentry. Used to cut pieces of wood into different shapes. This is usually done in order to join the pieces together and create a wooden structure or system. They operate by having a series of sharp teeth that are harder than the wood being cut. History Hand saws date back to the Neolithic period and were some of the first tools ever invented. Used to hack and saw at a material rather than simply cutting.
