A backsaw is a type of hand saw characterized by its stiffened back, which helps keep the blade straight during cutting. It typically has fine teeth designed for making precise cuts in wood, making it ideal for joinery and detailed work. Backsaws come in various sizes and tooth configurations, including the popular dovetail saw and tenon saw. The design of a backsaw allows for greater control and accuracy compared to other saws. The rigid back prevents the blade from bending, ensuring clean and straight cuts. Backsaws are commonly used in woodworking and carpentry, where precision is essential for fitting pieces together.
