What is a key sign that clippers may need sharpening?

1. Excessive noise during use

2. Pulling or snagging hair during use

3. Inconsistent cutting length

4. Frequent overheating

The correct answer is: Pulling or snagging hair during use

Pulling or snagging hair during the use of clippers is indeed a key sign that the blades may need sharpening. When clipper blades become dull, they are unable to cut hair cleanly and efficiently, leading to hair being pulled instead of cut. This can cause discomfort to the client and result in an uneven haircut. A sharp blade should glide smoothly through the hair without any tugging; any form of pulling indicates that the blade's edge has dulled and is not functioning as it should. While excessive noise during use, inconsistent cutting length, and frequent overheating can also signal issues with clipper performance, they are not as directly related to the sharpness of the blades. Excessive noise may indicate mechanical problems or a need for lubrication rather than blade dullness. Inconsistent cutting length can stem from a variety of factors, including technique or different guard lengths being used. Frequent overheating might suggest insufficient maintenance or an electrical issue rather than just dull blades. In summary, pulling or snagging hair is a clear and immediate indicator that the clipper blades require attention through sharpening.
