A coping saw is used for creating fine work such as the joints for a timber cornice. For such projects, no power tool is able to replace the accuracy of the coping saw. Coping saws can also be used to cut shapes out of the middle of a piece of wood or other material. To do this, first drill a small hole into the wood. Then remove the blade from the frame, place it through the drilled hole and reattach it to the frame. You can then proceed to saw out the desired shape. Crosscut Saw.
A scroll saw is a small electric or pedal-operated saw used to cut intricate curves in wood, metal, or other materials. The fineness of its blade allows it to cut more delicately than a power jigsaw, and more easily than a hand coping saw or fretsaw. Like those tools, it is capable of creating curves with edges, by pivoting its table. The scroll saw's name derives from its traditional use in making scrollwork, sculptural ornaments which prominently featured scroll-head designs.
