The short answer
Buy the Andis T-Outliner if you want the default and no decisions. A published 7,200 SPM magnetic motor behind a carbon-steel T-blade, corded, 14.5 oz, with a published two-year warranty. Buy the Wahl Detailer if you want to set the blade yourself. Its #2215 adjustable T-wide blade is the only adjustable blade in this pair, in a 9.5 inch body with a published eight-foot cord.

The two trimmers every shop owns
Walk into a barbershop and the outlining trimmer on the station is almost always one of these two. They do the same job - cut a hard line that a clipper cannot - and they take opposite positions on one question: who sets the blade?
Andis fixes it. A carbon-steel T-blade, set at the factory, behind a published 7,200 SPM magnetic motor. You take it out of the box and it cuts the line every barber cuts.
Wahl hands it to you. The #2215 adjustable T-wide blade moves, so the closeness is yours to set - including zero-gapping it, which is what professionals do and what beginners get wrong.

Where the Andis wins
- A published motor figure. 7,200 SPM is a number you can compare; most of this category publishes adjectives.
- Nothing to set. Out of the box it cuts the standard line, which is what most home users actually want.
- Published weight and warranty. 14.5 oz and two years, both stated.
- Ubiquity. Blades, parts and advice are everywhere because every shop runs one.
Where the Wahl wins
- The adjustable blade. Set the closeness yourself, tighten it as your hand improves, zero-gap it when you are ready.
- Guides in the box. Three extra-wide guides, which the Andis does not include at all.
- A published cord length. Eight feet, which matters when you are working behind your own head.
- A rotary motor, which holds speed under load differently from a magnetic one.
The honest cons, both ways
Andis: no guides in the box, no published body length, and carbon steel wants drying and oiling or it will spot. The fixed blade is also a ceiling - you cannot make it cut closer than Andis decided.
Wahl: an adjustable blade you set wrong is a trimmer that nicks you, it publishes no weight, and the corded 8081 is increasingly hard to find beside its cordless siblings - the roundup notes which versions are current.
The verdict
Home users and first-time buyers: the Andis T-Outliner. A fixed blade, a published motor and a two-year warranty is the least you can get wrong.
Anyone who already cuts hair and wants control: the Wahl Detailer. The adjustable blade is the reason professionals reach for it, and the guides in the box make it more useful out of the gate.
Whichever you buy, cleaning and oiling does more for the line it cuts than the motor figure does.

Our pickThe line every barber cuts
Andis T-Outliner T-Blade Trimmer (04780)
A magnetic motor published at 7,200 SPM behind a carbon-steel T-blade, corded, 14.5 oz, with a published 2-year warranty. It is the default outlining tool in professional use and it publishes the two figures that matter: motor speed and blade material. Corded is not a compromise here - a lineup is a stationary job.
- Material
- Carbon steel T-blade
- Made in
- Not published
- Refill
- Proprietary to the maker
- Warranty
- 2 years
- Assumed service life
- 2,600 uses
The arithmetic: 260 uses a year x 10 years of assumed service life = 2600 uses.
What it gets right
- Published 7,200 SPM magnetic motor - a real figure, which most trimmers do not give
- Published carbon-steel T-blade, hardened for cutting life
- Published 14.5 oz weight and 2-year warranty
- Corded, so there is no battery to fade mid-line
Flaws
- Corded, so it is tethered - and the cord length is not published
- Magnetic motors are louder and buzz more than rotary
- Carbon steel will rust if it is left wet; it needs oiling
- No guards included at this item number - it is an outlining tool, not a clipper
The working behind the 6.6
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.0
- Published motor speed and blade material remove the two biggest unknowns in this category (++), corded means no fade mid-line (+), but the cord itself is the friction (-) and carbon steel needs oiling (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 6.7
- 2 of 3 specifications a buyer would expect are published: material, warrantyLabel. Not published: madeIn. 2 / 3 x 10 = 6.7.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Andis T-Outliner 04780 published motor, blade and warranty.
2An adjustable blade you can set yourself
Wahl Professional 5-Star Detailer (8081)
A rotary motor behind the #2215 adjustable T-wide blade - the only adjustable blade on this page - in a 9.5 inch body with a published 8-foot cord and three extra-wide guides. Adjustable means you set the blade position yourself rather than buying a zero-gapped tool, which is the whole argument for it. Wahl publishes a 1-year warranty, half what Andis gives.
- Material
- #2215 adjustable T-wide blade
- Made in
- USA (assembled)
- Refill
- Proprietary to the maker
- Warranty
- 1 year
- Assumed service life
- 2,600 uses
The arithmetic: 260 uses a year x 10 years of assumed service life = 2600 uses.
What it gets right
- The #2215 blade is adjustable - the only one here you can set without replacing
- Rotary motor, which runs quieter and smoother than a magnetic one
- Published 8-foot chemical-resistant cord, the only published cord length on this page
- Three extra-wide T-shaped guides published, 1/16 to 3/16 inch
- Published as assembled in the USA
Flaws
- Published 1-year warranty against Andis's 2
- Wahl publishes no SPM figure at all, so the motor cannot be compared with the Andis tools
- An adjustable blade is one more thing to set wrong, and a badly set T-blade cuts skin
- Corded only
The working behind the 7.2
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 7.5
- An adjustable blade means one tool covers several gap settings (+), rotary motor and a published 8-foot cord (+), but no published SPM at all (-), a 1-year warranty (-), and an adjustable blade set wrong is a skin injury (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 10.0
- 3 of 3 specifications a buyer would expect are published: material, warrantyLabel, madeIn. 3 / 3 x 10 = 10.0.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Wahl 5-Star Detailer 8081 published motor, blade, cord and warranty.

Questions people actually ask
What is a lineup trimmer actually for?
Cutting a hard edge - the hairline, the temples, a beard's cheek line and neckline. A clipper rounds an edge; a T-blade cuts a line. The lineup roundup covers the category.
What does an adjustable blade get me?
You move the blade closer to or further from the guard yourself, which lets you set how close the trimmer cuts - and to zero-gap it if you know what you are doing. It also lets you set it wrong, which is the trade.
Does the published motor speed matter?
It is one of the very few motor figures anybody in this category publishes, which is why it is on this page. In use, blade sharpness and alignment matter more than the last few hundred strokes per minute.
Corded or cordless for lineups?
Corded is standard here and it is not a compromise: a lineup is a stationary job at a mirror and constant voltage keeps the blade speed constant. That comparison covers the wider trade.
Can I use either on my beard?
Yes - both are the right tool for a cheek line and a neckline. The neckline guide covers where the line belongs before you cut it.
Do I need one at all?
Only if you cut hard edges. If you buzz your head with guards and never define a hairline, a clipper alone is enough - the clipper roundup is the right page.
