Which technique allows for precision in cutting by opening and closing shears?

The technique that allows for precision in cutting by opening and closing shears is carving. Carving involves using shears in a way that enables the stylist to define shape and texture within the hair more intricately. This method requires the stylist to partially close the shears while moving through the hair, creating controlled and subtle changes rather than larger, non-specific cuts.

Carving is particularly useful for techniques that demand detail and precision, allowing for the suggestion of movement and layering in the hair. By manipulating the shears in this manner, hair can be sculpted more finely, giving a tailored, individualized look.

Other techniques, such as slicing and thinning, serve different purposes. Slicing is typically used to remove bulk and create softness by sliding the shears along the hair. Thinning focuses on reducing density without changing the overall length or shape significantly. Clipper cutting generally refers to using clippers rather than shears, which operates completely differently and is not aimed at precise shearing techniques. Each of these methods has its own applications and outcomes distinct from what carving achieves.
