A drag knife is a very specific type of blade for a computer numerical control (CNC) router. It’s a knife-shaped tool that attaches to the CNC router’s gantry and is used to make precision cuts. You attach the knife to the CNC router and then move the gantry across the workpiece, mimicking the motion of a pencil or pen. The CNC router moves the knife in a straight line and the knife follows the gantry’s path, making a very precise cut.
