🔍 Key Concepts

• Hand-held hacksaw operation (which direction normally does the cutting?) • Differences between rod, hardened, and flexible blades • How tooth set and material hardness affect cutting action

💭 Think About

• Think about how a standard hacksaw blade is designed to cut – does it usually cut on the push (forward) or pull (reverse) stroke? • Which blade type is most likely to have teeth or an edge that can remove metal in both directions rather than just one? • Consider which option might be a trick answer based on how most blades are actually used in practice.

✅ Before You Answer

• Verify which blade type is normally used for tough, hard materials and how that affects tooth design • Check whether any of these blade types are specifically made to be bi‑directional in cutting action • Confirm whether the way you mount a normal hacksaw blade could realistically make it cut effectively on both strokes
