The BaBylissPRO FXONE All-Metal Black Skeleton Trimmer FX799MBE is a professional cordless outlining trimmer built on the FXONE interchangeable battery system.

Why barbers reach for it
The FX799MBE is the detailing half of the FXONE kit. Where the clipper removes bulk and blends, the skeleton trimmer draws the line: sharp outlines, edge-ups, necklines and beard work. The fully exposed T-blade sits 360 degrees open so you can see exactly where the cutting edge meets the skin, and the high-torque digital motor holds its speed for a clean, chatter-free line. Because it runs on the same FXONE battery as the clipper and shaver, one charged battery moves across your whole kit.
Key features
- Long-life high-torque digital motor at 7,200 RPM, driving 1,137,600 cutting actions per minute for crisp, chatter-free lines.
- Fully exposed zero-gap blue Titanium and DLC standard-tooth T-blade, 40 mm wide and 1.6 mm, for close outlines with 360-degree visibility.
- Universal snap-in FXONE lithium-ion battery with a quick-release button, shared with the FX899MBE clipper and FX79FSMBE shaver.
- Up to 3 hours of cordless runtime from a 2-hour charge, with a 4-stage LED ring showing the level at a glance.
- Improved all-metal housing with a knurled barbell grip and a hidden hanging hook for control and quick storage.
- Removable magnetic hair-pocket cover for fast cleaning between clients.
- Zero-gap adjustable for the closest lines, with a built-in design that helps keep the blade running at a lower temperature.
- Dual-voltage universal charging base rated 100-240V for use anywhere.
What to expect in daily use
This is a detailer, not a bulk cutter. Straight out of the base the trimmer feels dense and balanced, and the exposed T-blade gives you a clear view of the line you are carving. Zero-gapped, it lands crisp edges and sharp corners; run it up a neckline or around the ear and the digital motor does not bog down. Drop the battery onto the base, snap in a spare and keep detailing, with the LED ring showing where each battery stands.
Who it is for
- Professional barbers who want a dedicated all-metal trimmer for lines, edge-ups and beard detail
- Anyone already on the FXONE battery who wants one cell across clipper, trimmer and shaver
- Detailers who want an exposed 360-degree T-blade for maximum sightline on the cut
- Mobile and travelling pros who need a 100-240V base that works anywhere
Who it is not for
- Barbers who mainly remove bulk, taper and fade -- the FX899MBE clipper is the tool for that
- Anyone wanting a corded trimmer; the FX799MBE runs cordless from the FXONE battery only
- Shoppers after the cheapest starter trimmer rather than a professional all-metal detailer
Professional tip
Zero-gap the exposed T-blade in small steps and test the closeness on your own arm before you work a hairline. A skeleton trimmer wants a light hand: let the blade do the work, because pushing it into the skin is what causes irritation and lifts hairs unevenly. Keep the blade oiled and the line stays sharp all day.
How to use it
- Charge the battery fully on the dual-voltage base before the first use.
- Snap the battery into the trimmer until the release button clicks home.
- Oil the blade, run the trimmer for a few seconds and wipe off the excess.
- Work your outlines and edge-ups with the corner of the exposed T-blade, keeping a light touch.
- Zero-gap the blade only as close as the client's skin comfortably allows.
- Brush the blade clean, lift the magnetic hair-pocket cover to clear clippings, oil again and return the battery to the base.
Care, maintenance and compatibility
Brush hair off the blade after every client and lift the magnetic hair-pocket cover to clear trapped clippings. Oil the blade daily, because an exposed T-blade dulls fast and loses its zero-gap edge when dry. Wipe the all-metal housing with a dry cloth only. The original blade is the FX707BL, and the FXONE battery is interchangeable across the line, so it also powers the FX899MBE clipper and FX79FSMBE shaver; charge it on the included dual-voltage base and store the trimmer somewhere dry.

Frequently asked questions
Is the FX799MBE a trimmer for lines, or can I use it to cut bulk hair?
It is a skeleton outlining trimmer, built for crisp lines, edge-ups, necklines and beard detail with its fully exposed T-blade. For removing bulk, tapering and fading, use the matching FX899MBE clipper. The two are designed to work together as one FXONE kit.
How does the interchangeable FXONE battery work?
The lithium-ion battery snaps into the trimmer and releases with one button. It is the same battery used across the FXONE line, so it also fits the FX899MBE clipper and FX79FSMBE shaver. Keep a second battery charging on the base and swap it in when the first runs low to detail with no downtime.
Can I zero-gap the exposed T-blade, and is that safe on skin?
Yes, the blade is zero-gap adjustable for the closest lines. Move it in small steps and test on your own arm first, because set too aggressively an exposed blade can nick or irritate skin, especially on sensitive necklines. Keep a light touch and let the blade do the work.
Can I use the FX799MBE abroad?
The charging base is rated 100-240V, so it works on mains power worldwide. You only need a simple plug-shape travel adapter, not a voltage converter. The trimmer itself always runs from the FXONE battery, so you are never cutting straight off the wall.
Which replacement blade fits, and do I still oil it?
The original blade is the FX707BL blue Titanium and DLC T-blade. Even with its lower-temperature design, an exposed blade still needs regular oiling: a drop before and after each use, run for a few seconds and wipe the excess. A dry blade dulls fast and loses its zero-gap edge.
Does the trimmer get hot during long sessions?
Like any trimmer it warms up in continuous use, which is normal. The blue Titanium and DLC blade is designed to run at a lower blade temperature, and regular oiling keeps friction down. If the blade feels warm, add a drop of oil and let it run for a few seconds.
Is it cordless only, and how do I keep it in good shape?
It runs cordless from the snap-in FXONE battery; there is no corded mode, and the battery charges on the included base. Brush the exposed blade after every client, lift the magnetic hair-pocket cover to clear clippings, wipe the metal body dry, oil daily and store it somewhere dry.
