A very short comb attachment, usually 1 to 5 mm, made for holding a designer stubble rather than for trimming a beard.
Ordinary beard combs start around 3 mm (0.12 in) — an eighth of an inch — and go up. Stubble combs cover the band below that, between roughly a thirty-second and a sixteenth of an inch, which is where a two- or three-day look lives.
The counter-example on this site is the clearest argument for them: the Braun AIO3545 kit at $100 begins at 3 mm (0.12 in), so nothing shorter than a short beard is reachable with it at all. A stubble is out of range on a tool with fourteen settings.
The Philips OneBlade on this site ships with three at 1, 3 and 5 mm (0.20 in). The Multigroom 3000 lists two at 1 mm (0.04 in) and 2 mm (0.08 in).
Whether you need them depends on the tool, and the distinction is worth getting right: a precision wheel does not remove the comb, it MOVES it. The Braun BT5525 steps half a millimeter per click and the BT9545 a quarter, across one attachment that stays on the machine — so you get the whole stubble band without swapping anything, which is a different thing from having no comb. See what the lock wheel is for.
Where combs are used, the thing that matters is that they clip fully home. One sitting slightly proud cuts longer along that edge, which is a common cause of an uneven stubble.
