Which saw has replaceable blades suited for cutting metal and other non-wood materials?

• A. Coping Saw
• B. Hack Saw
• C. Back Saw
• D. Combination Saw

Answer: (B)

Cutting metal and other non-wood materials relies on a blade designed for hard substances and a frame that keeps the blade under tension for straight, controlled cuts. The hacksaw uses a replaceable blade in a rigid frame that tensions the blade, allowing you to apply steady force and cut through metal cleanly. You can swap blades for different non-wood materials, keeping the teeth appropriate for metal, plastic, or similar tough substrates. The other saws are aimed at wood: coping saws have very flexible blades for curved wood cuts, back saws rely on a stiff back for precise woodworking joints, and combination saws are general-purpose for carpentry with blade configurations not optimized for metal. So the hacksaw is the best fit for cutting metal and other non-wood materials.
