🔍 Key Concepts

• Purpose of chalking a file (what problem it prevents) • Which metals are soft and gummy versus hard and brittle when filing • How metal particles behave in file teeth for different materials

💭 Think About

• Think about which of these metals is most likely to quickly clog the teeth of a file when you stroke it across the surface. • For which metal would you be most concerned about metal packing into the file and scratching or gouging the work instead of cutting cleanly? • Which listed metal is least likely to pack and smear into the file teeth, so extra prevention might not be as critical?

✅ Before You Answer

• Recall that chalking is done to reduce clogging (pinning) of the file teeth. • Identify which options are very soft and smear easily when worked (those usually need more chalking). • Identify which option is harder and cuts cleanly without packing the teeth as much.
