Quick answer

Snap the comb attachment onto the Baby Beast Trimmer blade until it seats flat, then glide the trimmer against the direction of hair growth using light pressure. Start with the longest comb for your first pass, then step down to shorter combs or the precision blade for edges. Clean the comb and blade after every use so the next attachment clicks on securely.

What the comb attachments actually do

The comb attachments act as depth guides: they hold the blade a set distance from the skin so you remove hair evenly instead of cutting too close in one pass. That makes them the right choice for beard bulk work, hairline blending, and body areas where you want a uniform length rather than a bare-skin finish. The included precision blade is the opposite tool: it gives you extra control for detailed or intricate areas, so keep it for edges and touch-ups rather than large areas.

Before you start: fit and check the attachment

Work with dry or towel-dried hair so the comb can move through it without dragging. Comb the hair in the direction you want it to lie, then decide your target length before you switch the trimmer on. If you are unsure, begin with a longer comb and shorten in stages; you can always remove more hair, but you cannot put it back.

  • Seat the comb on the blade and press until it sits flat with no gap or rocking.
  • Tug gently upward on the comb to confirm it will not slip mid-pass.
  • Check the blade area for trapped hair or debris before every use.

Direction, pressure, and speed

Move the trimmer against the direction of hair growth for an even cut, and keep the comb flat against the skin rather than tilting it. Let the trimmer do the work: pressing harder does not cut closer with a comb fitted, it only increases friction and the chance of irritation. For curved areas such as the jawline, neck, or underarms, use short strokes and reposition your hand instead of forcing one long pass.

Cleaning and storage between uses

Blades pop off for easy cleaning, and the combs should be rinsed and dried before they go back on. A comb with hair packed into the teeth will not sit flat, which changes your cutting depth without you noticing. Store the trimmer with the comb removed so the blade and comb teeth keep their shape.

Step-by-step: using the Baby Beast Trimmer comb attachments

  1. 1. Start with clean, dry hair: Wash and dry the area, then comb the hair in its natural direction so the trimmer can pass through without snagging. Mistake to avoid: trimming damp, tangled hair, which makes the comb drag and produces an uneven line.
  2. 2. Fit the longest comb first: Press the comb onto the blade until it sits flat with no gap, then tug gently to confirm it is locked in place. Checkpoint: if the comb rocks or lifts at one corner, remove it and reseat before switching the trimmer on.
  3. 3. Trim in the direction opposite hair growth: Use short, overlapping strokes and keep the comb flat against the skin. Move your hand rather than tilting the trimmer around curves. Mistake to avoid: pressing hard to 'get closer' — with a comb fitted, extra pressure adds friction, not a shorter cut.
  4. 4. Step down comb sizes in stages: Stop, brush away loose hair, and check the length in good light before moving to a shorter comb. Checkpoint: if you are unsure, stay on the current comb for one more pass instead of jumping two sizes down.
  5. 5. Switch to the precision blade for edges: Remove the comb and use the precision blade for hairlines, necklines, and detailed or intricate areas, working slowly with the blade flat. Mistake to avoid: using the precision blade for bulk removal, which takes longer and raises the risk of an uneven line.
  6. 6. Clean the comb and blade, then store: Pop the blade off, rinse the comb and blade, dry both fully, and store the trimmer with the comb removed. Next step: check the comb teeth for bent or missing sections before your next trim so your depth stays consistent.

Product facts

  • Baby Beast Trimmer with Precision blade | 4 Comb Attachments included: The Baby Beast Trimmer ships with 4 comb attachments and a precision blade; the hardened steel blades give a comfortable close-to-skin trim for hair types from very fine to very coarse, and the blades pop off for easy cleaning. You get several depth options plus a detail blade in one tool, so you can bulk-trim with a comb and switch to the precision blade for edges without changing devices.
  • Skull Shaver Baby Beast Trimmer-3SUM: The Skull Shaver Baby Beast Trimmer 3SUM is described as an all-in-one grooming solution for beard trimming, hairline shaping, body hair, and below-the-belt sensitive areas. If you want one trimmer to cover several zones, the 3SUM setup is the more complete starting point, while the standard Baby Beast Trimmer suits users who mainly need beard and line work.
  • Pitbull Foil Shaver Attachment | Compatible with all Skull Shaver models: The Pitbull Foil Shaver Attachment is compatible with Pitbull, Butterfly Kiss and Palm Shavers and is sold as an attachment only; the foils generate subtle vibrations that lift hair follicles from skin and shave without pulling or nicking. A foil attachment is a different finish than a comb-guided trim, so use it for close work on the chin, neck, underarms, behind the knees, or bikini areas rather than as a replacement for the trimmer combs.
