Definition
Noun: A back saw is a type of handsaw characterized by a rigid metal or steel strip (called a "back") running along the top edge of its blade. This reinforcement makes the blade stiff, allowing for more precise, straight cuts, typically used in woodworking for joinery like dovetails or miters.
