SCIE

Scie is the French word for a saw, a cutting tool that uses a toothed blade moved to shear material. Saws are used to cut wood, metal, plastic and other materials, and they can be operated by hand or powered by machines. The general principle is to remove material along a line by repeated tooth action.

There are many forms of scie adapted to different tasks. Scie à bois refers to a handsaw used for wood, typically with a broad blade and larger teeth. Scie à métaux is designed for metal work and features a finer, hardened blade that resists wear. Other common types include the scie égoïne, a fine-toothed wood saw for precise work; the scie à chantourner, a fret saw for intricate curves; and the frame or bow saw (scie à archet), which uses a flexible blade held in a frame. Powered variants include the scie circulaire (circular saw) and the bandsaw, which are used for rapid or long, straight cuts.

Construction and use: blades are usually made of steel and can be carbon steel or high-speed steel. The tooth configuration determines cutting behavior: rip teeth are suited for cutting along the grain in wood, while crosscut teeth are optimized for cutting across the grain. A blade is clamped in a handle or frame and kept under tension; maintaining sharp teeth and proper alignment improves efficiency and safety. Regular maintenance includes cleaning, occasional sharpening or replacement, and using appropriate lubricants or guards for powered models.

History and context: saws have ancient origins, with evidence of early bronze and iron specimens. Over centuries, designs evolved to address different materials, cutting requirements, and precision tasks, leading to a diverse family of scie forms used in woodworking, metalworking, and construction.
