Soften the transition rather than the position: use a comb one or two settings shorter along the border before going to bare skin, so there is a gradient instead of a wall.
A hard edge is a boundary between hair and no hair with nothing in between. It looks precise for a few days and then the regrowth sits in the shaved area.
Two ways to soften. Use a comb one or two settings shorter along the border before going to bare skin, so there is a gradient. Or set the edge where the growth naturally thins, rather than where you would draw it.
The neckline follows the same logic for the TRANSITION, and not for the position. Where the line sits is a separate decision and it is not negotiable the way the cheek is: two fingers above the Adam’s apple, curving to follow the jaw. What this page is about is the half-inch above that line — take it down in two steps rather than one, and the regrowth has somewhere to arrive.
The tool that makes this easier is a trimmer with a fine wheel, because a two-step gradient is two clicks rather than two attachments. The Braun BT5525 moves half a millimeter per click and the BT9545 a quarter, and both lock so the setting does not drift while you work along an edge.
