Which tool is commonly used for blending hair at the edges?

Thinning shears are designed specifically for blending hair at the edges, helping to create a softer and more natural transition between different lengths of hair. These tools have notches in the blades that allow them to cut only some of the hair while leaving the rest intact, which is ideal for removing bulk and providing a blended finish. This technique is particularly useful in haircuts that require subtle blending around the perimeter to avoid harsh lines, especially in layered styles.

In contrast, razors are typically used for cutting textured layers or creating softer edges but do not blend in the same manner. Shears are the standard cutting tool in hairdressing, used for various types of cuts but not specifically for blending. Clippers, while practical for cutting and shaping hair, are not ideally suited for achieving a blended look at the edges, as they usually create more defined lines rather than soft transitions. Thus, thinning shears stand out as the most effective tool for blending hair seamlessly at the edges.
