Which practice is correct when using a hacksaw?

• A. Make sure the teeth are pointing away from the forward cut.
• B. The blade should be loosened when cutting.
• C. The teeth should point toward the forward cut.
• D. The hacksaw blade should be used with a dull edge.

Answer: (A)

The key idea is how a hacksaw blade is oriented so the teeth do the cutting in the intended direction. The teeth are designed to bite when you push the blade forward, so they should face in the direction you are advancing the cut. When the teeth point away from the forward cut, you get a clean, efficient bite as you push the blade, which helps prevent binding and keeps the cut under control. Keeping the blade properly tensioned and sharp is also important for safety and control, while loosening the blade, having the teeth face the wrong way, or using a dull edge would make cutting harder, less accurate, and more risky.
