A saw is a tool with a hardened steel toothed blade, intended to cut materials such as wood, stone, metals... It is operated by various means such as muscular force, electricity or water. .


The Greeks attributed the invention of the saw to Talos, Daedalus' nephew. It was this invention, among others, that drove his jealous uncle to murder him. Of course, Daedalus is a myth. In the Neolithic, the saw would have been preceded by thin rasps mounted on pieces of wood. However, its primitive form asserts itself in the Bronze Age. Then, in the Iron Age, the saw specialized in different forms. Flat and hammered iron is gradually being replaced by steel. During ancient Egypt the models multiply. As for the saw representations, they are later: in the XIIth dynasty and another in the XIXth dynasty. They are found in the burial chambers of Egyptian Thebes. Similarly, the many pieces of furniture from ancient Egypt testify to the frequent use of the saw. The Hierapolis sawmill is the oldest known machine using a connecting rod-crank system. During Roman Antiquity some appeared and remained in common use until the 15th century. Short saw: considered the ancestor of the handsaw. long saw to debit: resembling the saw of the long sawyers. Medium frame saw. Crosscut saw. single handle back saw.


Types of saws

Hand Saws

Crosscut saw: saw with sharp teeth for cutting wood across the grain. It is opposed to the edger or rip saw. The "ryoba", one of many Japanese saws, has one side of the blade sharpened for cross-cutting and the other side sharpened for edging. Edging saw: saw whose teeth are sharpened to cut the wood in the grain. It opposes the crosscut saw. Many saws feature versatile sharpening. Coping saws are necessarily versatile whereas handsaws are often so for marketing reasons. Japanese saws are rarely versatile, which is more efficient. handsaw: large western saw whose blade is not stretched by a frame. It is intended for straight cuts and can be sharpened for cross-cutting or edging. Frame saw: saw whose blade is stretched in a wooden frame. It is no longer used much and has been replaced in many workshops by the handsaw or the Japanese saw. This is the most common saw, as it is for domestic use. Coping saw: saw used to cut curves. It can be frame or handsaw. Keyhole saw: small handsaw whose blade is thin enough to be used for scrolling. Bocfil saw: saw with a very thin blade (like a wire) used for fretwork in precision work (marquetry, model making). The blade is stretched in a U-shaped metal frame. Japanese saw: has the particularity of being pulled to cut unlike the handsaw used in the West. This inverted toothing allows for much finer blades and therefore requires less force than a handsaw. These saws enjoy a high reputation and are increasingly used in the West. Their disadvantage is to bring the sawdust back to the kerf and to require less obvious wedging of the piece of wood. The Japanese climb on the piece of wood which is raised by a small easel. Its sharpening is also very difficult, because the teeth are hardened and have several cutting edges. The blades, on the other hand, are often interchangeable. The handle is held with two hands. The right leading hand often goes to the back, unlike the saber. Back saw:
