Rubbing a clean file across the edge of a new file to remove sharp edges before use is called what?

• A. Deburring
• B. Conditioning
• C. File Prepping
• D. Priming

Answer: (C)

Rubbing a clean file across the edge of a new file to remove sharp edges before use is about getting the tool ready for safe, effective use. New files often have sharp edges or burrs that can catch, gouge skin, or produce an uneven cut. By smoothing that edge, you prevent accidents and ensure the file will bite evenly when you work. This preparatory step is called file prepping. It’s different from deburring, which refers to removing burrs from a finished part after machining, and it’s not about conditioning or priming, which relate to other processes.
