How do barber's shears differ from a razor?

Barber's shears primarily serve the function of cutting and shaping hair, making them an essential tool for barbers in achieving various hairstyles. Unlike razors, which are often used to create texture or to shave, shears provide precision in cutting lengths and layering, allowing the barber to execute a clean cut with controlled techniques. This versatility is critical for both traditional and modern hairstyling.

In contrast to the other options, while shears can also be used for texturizing in certain techniques, their main role centers around effective hair cutting and shaping. The statement regarding razors relates to their use in shaving rather than focusing solely on cutting hair, which emphasizes the different purposes each tool serves. Additionally, the maintenance aspect is not the primary distinguishing characteristic between shears and razors in a practical sense, as both require proper care to maintain their effectiveness. Overall, the primary distinction lies in the function of cutting and shaping hair attributed to shears.
