What is the purpose of using a straight razor in barbering?

The use of a straight razor in barbering primarily serves the purpose of achieving precise hair cutting and creating clean lines. A straight razor allows barbers to make highly accurate cuts, which is essential for styling and finishing techniques that involve detailed work. The sharp blade enables barbers to execute clean edges, especially in styles that require straight lines and defined shapes, such as undercuts, fades, or sharp beard lines.

Using a straight razor also gives the barber more control over the cut compared to using other tools, allowing for the subtle nuances that can dramatically enhance the overall appearance of a hairstyle or facial hair. The technique involved in using a straight razor, which requires skill and practice, greatly contributes to the precision that is sought after in professional barbering.
