Which tool does not need to be disposed of after one use?

Nippers are a tool that can be sanitized and reused, unlike some of the other tools listed which are single-use items. Nippers are typically made of stainless steel and can withstand the high-temperature sterilization process necessary to effectively disinfect them after a client. This allows them to be reused safely, provided they are thoroughly cleaned and sterilized between clients.

In contrast, a spatula is usually a disposable item since it’s meant to apply wax and is not designed for sterilization after use. Scissors can be reused, but they require careful maintenance and sanitization protocols, similar to nippers; however, they are often categorized separately due to their design and function. A scalpel, commonly used in other beauty or medical contexts, should be disposed of after one use for safety and hygiene reasons.

Thus, nippers being reusable without needing disposal after one use makes them a suitable choice in a professional waxing setting.
