Käsisaha

Käsisaha is the Finnish word for a handsaw. A handsaw is a saw that is operated by hand rather than by a motor. It typically consists of a blade with a serrated edge and a handle. The blade is usually made of steel and is designed to cut through various materials, most commonly wood. The teeth on the blade are angled and shaped to remove material as the saw is moved back and forth.

Handsaws come in various types, each designed for specific tasks. Common types include crosscut saws, which are used to cut across the grain of wood, and ripsaws, which are used to cut along the grain. There are also specialized handsaws for cutting metal, plastic, or plasterboard. The length and width of the blade, as well as the size and spacing of the teeth, vary depending on the intended use.

The operation of a handsaw involves placing the blade against the material to be cut and moving the saw back and forth with steady, controlled strokes. The user applies pressure to guide the saw and to facilitate the cutting action. Proper technique is important for efficient cutting and to avoid damaging the saw or the material. Handsaws are fundamental tools in woodworking, construction, and general DIY tasks.
