🔍 Key Concepts

• Proper use of a hacksaw when beginning a cut • How to control the blade so it doesn’t wander off the mark • The purpose of preparing the workpiece before sawing

💭 Think About

• Which option helps the blade stay on the line right at the beginning of the cut? • Which choices might actually make the blade slip, bend, or bind instead of guiding it? • Think about what a machinist or shipboard mechanic would do to mark or start a very precise cut in metal.

✅ Before You Answer

• Eliminate any option that would likely damage the blade or the frame. • Ask yourself which step a careful worker would take before picking up the saw to make sure the cut starts exactly where intended. • Consider whether adding something slippery to the blade would make it easier or harder to control the start of the cut.
