Answer:
Backsaw.
Explanation:
A backsaw can be defined as a short handsaw with a rectangular blade and a reinforced metal rib (stiffening rib) along its back so as to make the blade perfectly straight and allow for better control. Also, the reinforced metal rib (stiffening rib) helps to give a more precise cut better than other types of handsaw and as a result of this, it is mostly used in woodworking such as cutting tenons, mitres, or dovetails.
Hence, the extra band of metal across the back of a backsaw stiffens the saw to help prevent bending and inaccurate cuts.
