handsaw

A handsaw is a hand-operated cutting tool used primarily for woodworking. It consists of a metal blade with teeth, attached to a handle that is held by the user. The blade may be rigid or flexible, and its teeth are shaped and spaced to suit specific cuts. Handsaws are designed for manual use, though some modern variations incorporate lightweight frames to aid tension and control.

Common types include rip saws, which have teeth shaped to pull fibers apart for cutting along the grain; crosscut saws, with teeth optimized for cutting across the grain to produce cleaner ends; back saws (including tenon saws and dovetail saws) that have a stiffening spine for precise joinery; frame saws, which use a narrow blade mounted in a frame for thin kerfs and resawing; and coping or keyhole saws for curves and small openings. Each type evolves to balance speed, accuracy, and kerf width.

Construction and maintenance focus on blade material (often high-carbon steel), tooth ergonomics, and the ability to keep teeth sharp and evenly set. Teeth can be sharpened or re-tipped for different cuts. Regular inspection for rust, blade tension (in frame saws), and a secure, comfortable handle enhances performance.

Use involves clamping the workpiece, marking the cut, and guiding the blade with steady, even strokes. Cuts are started carefully to prevent wandering, with attention to keeping the blade perpendicular to the surface and avoiding binding. Handsaws remain a fundamental tool in woodworking for tasks ranging from rough framing to fine joinery.
