Answer Details

Name the tool shown in Fig. 1

Tenon saw [1]. The tenon saw has a rectangular blade stiffened along its top edge by a folded steel or brass spine (visible at the top of the diagram). This rigid back keeps the blade perfectly straight, allowing precise, controlled cuts. The teeth along the lower edge are fine, giving a clean finish. It is used for making straight cuts in wood, particularly when cutting joints such as tenon joints, halving joints, and bridle joints.
