🔍 Key Concepts

• Common parts of a hand file used in metal work • How files are designed to protect adjacent surfaces from damage • Terminology used in basic tool safety

💭 Think About

• Which term describes an edge that is intentionally made without cutting teeth so it will not remove material? • Think about which word is commonly associated with safety or protection when working close to a finished surface. • Eliminate any answers that simply describe shape or general smoothness rather than a specific tool-safety feature.

✅ Before You Answer

• Verify which term in the choices is used in trade/industrial contexts to mean a non-cutting edge on a file. • Check that the term you choose is specifically about preventing accidental cutting, not just describing how the edge looks. • Make sure the word you select is standard hand-tool terminology found in basic shop or seamanship tool references.
