The Wahl Beret Stealth is Wahl Professional's slim cord/cordless trimmer for the outline, the beard line and detail work. WAHL sums up its job in one line: “Designed for outlines, detail work and contours - cuts very close to the skin”. The blade comes off: it is a detachable, chrome-plated blade, 32.5 mm wide. It runs up to 75 min on a lithium-ion battery.

Why the Beret Stealth
A cut in the chair runs in a fixed order: the clipper takes the bulk and the taper, the trimmer sets the outline and the beard line, and the foil shaver finishes. Three things fit this trimmer to the job: a body WAHL calls “Super-slim”, a blade that comes off for cleaning, and short guides for blending the beard into the line. We would put it on the station of a barber who lines up all day and likes to clean underneath the blade.
Who it is not for
- Taking the bulk off or cutting a taper - that is a clipper's job: the Wahl Magic Clip Cordless Black
- A skin-smooth head shave - that is a foil shaver's job: the Wahl Vanish Shaver
Professional tip
Work the outline with the blade flat and the skin stretched with your free hand. Use the guides to blend beard length back into the line, never for bulk. Our rule at the chair is simple: the guide blends, the bare blade draws the line.
Care and maintenance
After each client, switch off and brush the loose hair from the housing and the blade with a dry brush. From time to time, with the trimmer off, take the blade off and brush out the hair underneath before you refit it. Oil the blade often, with Wahl clipper oil only: one drop in the centre of the moving top blade and one on each end, then switch the trimmer on to spread it and wipe off the excess. Every so often, oil the heel of the blade too. Wipe the housing only with a soft, slightly damp cloth, never with solvents, bleach, benzene or thinner. If it cuts worse despite regular cleaning and oiling, the blade set needs replacing. The Wahl Special Blade Oil 200ml is the bottle for the station; the Wahl Oil Tube 10ml is the tube for your case.

How long does the trimmer run on a charge?

Which guides come with the trimmer?
Guides of 3 mm, 6 mm, 10 mm and 13 mm. Use them to blend beard length back into the line, and work without one for the outline itself.
What is the trimmer designed for?
In WAHL's words: “Designed for outlines, detail work and contours - cuts very close to the skin”. Taking the bulk off is a clipper's job, and a skin-smooth head shave is a foil shaver's.
How do I clean and oil the trimmer?
Switch it off and unplug it. After each client, brush the loose hair from the housing and the blade with a dry brush, and from time to time take the blade off and brush out underneath. Oil the blade often with Wahl clipper oil: one drop in the centre of the moving top blade and one on each end, run it briefly and wipe off the excess. Wipe the housing only with a soft, slightly damp cloth, and never rinse it under the tap.
