Answer:
A pair of shears that feels uncomfortable in a hairstylist's hand is poor in the area of ergonomics. Ergonomics is the science of designing tools and equipment that are comfortable and easy to use. Poor ergonomics can lead to fatigue, discomfort, and even injury over time. In the case of hairstylists, poorly designed shears can lead to discomfort, fatigue, and decreased accuracy in cutting hair.
