Which technique is recommended for achieving a clean, sharp neckline?

Using the clipper over comb technique is recommended for achieving a clean, sharp neckline due to its precision and ability to create well-defined lines. This method involves using a clipper blade in conjunction with a comb to lift the hair while cutting it, allowing for greater control over the length and shape of the neckline.

Clippers can effectively cut through hair and provide a more uniform length compared to scissors. The comb serves to guide the hair into the desired position, making it easier to maintain a clean and sharp appearance. This technique is particularly useful in beard and neck shaping, where a defined edge is desirable for a polished, professional look.

Other techniques, while they have their own merits, may not achieve the same level of sharpness and definition. For instance, scissors over comb can create a softer edge and is less effective for quickly outlining a neckline. Razor cutting is more appropriate for adding texture rather than defining lines, and using fingers and shears might lead to a more casual or less structured outcome.
