What is backsaw?

A backsaw is a type of handsaw designed for making precise and accurate cuts. It is characterized by a stiffening brass or steel back along the top edge of the blade which helps to keep the blade straight and prevent it from bending during use.

Backsaws typically have a thin, narrow blade with fine teeth that are designed for cutting across the grain of wood. The blade is usually around 8-14 inches long, making it ideal for detailed or intricate woodworking projects, such as joinery or fine cabinet making.

There are several types of backsaws, including tenon saws, dovetail saws, and carcass saws, each with its own specific use and design. Backsaws are often used in conjunction with a bench hook or miter box to ensure accurate and precise cuts.

Overall, backsaws are popular among woodworkers and carpenters for their precision and ability to create clean and accurate cuts in a variety of woodworking projects.
