Using dull blades during a barber shave should be avoided because they increase the risk of irritation and cuts to the skin. A dull blade does not provide a clean cut, which can lead to tugging and pulling on the hair instead of a smooth shave. This can cause discomfort for the client and increase the likelihood of nicks and abrasions.

Conversely, sharp blades are essential in achieving a close and effective shave while minimizing the chance of injuries. Exfoliating the skin beforehand is a beneficial practice as it helps to remove dead skin cells and can prevent ingrown hairs. Similarly, applying shaving cream is an important step that helps to lubricate the skin and hair, ensuring a smoother glide for the blade and further reducing the risk of irritation. Therefore, ensuring that blades are sharp is crucial for a safe and comfortable shaving experience.
