What type of nail tool should be discarded after each use?

The emery board should be discarded after each use because it is designed to be a single-use tool. Unlike metallic tools such as cuticle nippers, which can be disinfected and reused, emery boards are typically made from materials that cannot be effectively sterilized. They often accumulate bacteria and other pathogens after one use, making it unsafe to reuse them for nail services. Disposing of emery boards after use helps maintain hygiene and prevents the spread of infections or diseases between clients. This practice is essential in ensuring a safe and clean environment in nail care and cosmetology.
