Hand saws are hand-held tools, either powered or manually-driven, that are designed to cut through softer materials. They accomplish cutting using a hard, serrated blade, or by using a wire with an abrasive edge.
Deburring and chamfering tools are used to clean edges after machining. Deburring tools remove flashing and other unwanted edge properties caused by cutting or machining. A chamfer is a beveled edge at the intersection of two surfaces so the surfaces are typically at 45 degrees.
