Foil shavers
Foil shavers cut in straight lines behind a perforated screen, which suits a face shaved daily. These three run from three blades to five, and the amount each maker publishes varies more than the price does.
The Panasonic ES-RT37 publishes everything: three blades, arc-shaped foils shaped for under the chin, a thirty-blade pop-up trimmer, one hour to charge, fifty-four minutes of use, washable under running water.
The Braun 3040s has two things the Panasonic does not have: a five-minute quick charge, and a narrow head that reaches under the nose. Braun also states where it is made. There is no amazon.com offer for this reference at present.
The Panasonic ES-LV67 is five blades on a linear motor at 70,000 cutting actions a minute, with a head that moves in sixteen directions and a beard density sensor. Panasonic states it shaves as on the first day for five years, and names how that was tested — artificially aged units against new ones.
We would not choose between a foil and a rotary on price. They are different mechanisms for different faces, and buying the cheaper family is how people end up disliking a perfectly good shaver.
Where the format is at its best: short growth, flat areas, straight strokes.
The pop-up trimmer on most foils handles sideburns and the mustache line. It is the reason the tool is often enough on its own.
With foam, on models rated for it. Many users find it more comfortable, and it changes the cleaning routine.
The format's weak point: foils prefer daily use, and several days' growth needs a trim first.
| Your situation | Foil | Rotary |
|---|---|---|
| Daily, flat areas | Generally closer | Slightly less close |
| Hair growing in several directions | Struggles | Better |
| Several days' growth | Trim first | Copes better |
| Edges and mustache line | Pop-up trimmer | Often less precise |
A foil is thin and easily damaged, and the whole shave depends on it being intact. Cleaning gently and replacing the foil and cutter together is what keeps the shave close and comfortable.

2 foils + MicroComb · 3 flex blades · 100% waterproof · 45 min · made in Germany
Two Braun foils either side of a middle trimmer, three flexing blades, a MicroComb that Braun states catches more hair per stroke, a body it states is 100% waterproof, and forty-five minutes of runtime with a five-minute quick charge.
Best for: A daily shave, wet or dry, with a narrow head for under the nose.
5 blades · linear motor 70,000/min · 16D flex head · beard sensor
Five blades, a linear motor at 70,000 cutting actions a minute, and a head that moves in sixteen independent directions. Panasonic states the steel blades shave as on the first day for five years, tested against artificially aged units.
Best for: A thick beard shaved daily, where the number of passes is the actual complaint.
≈ $185
More blades cover more skin per stroke, and make the head wider — which is a disadvantage under the nose. Three is enough for most faces shaved daily; five shortens the job on a dense beard.
On the morning the shaver is flat, it is the only specification that matters. Braun states five minutes for one shave; Panasonic states three minutes on both its higher models. The entry Panasonic does not publish one.
Generally on flat areas, yes, which is its main argument. On contours and hair growing in several directions a rotary follows better.
In straight strokes against the direction of growth, with light pressure. Circles belong to the rotary, and pressure only causes irritation.
On the maker's schedule, and always together with the cutter, since they wear as a matched pair.
Only on models explicitly rated for wet use. A washable head means rinsing, which is not the same permission.
Usually a worn foil and cutter pair. Pressing harder is the instinctive response and it makes irritation worse without helping.
Replace it. A dented foil lets the cutter come too near the skin, and no amount of care compensates for that.
Good on: A daily dry or wet shave, with the head rinsed at the tap afterwards.

Blades, combs and oil from the same aisle, at the price we recorded. Check they fit the clipper you pick before ordering: it depends on the blade mount and the part number, which the listing states.

The clippers and shavers here come from the catalog of this site. Specifications are the published ones, from the maker and from the Amazon page; prices are the Keepa figure for the date below, and both change. Ranking rests on declared specifications, on stated strengths against stated limits, and on price. Nothing here has been used on hair by us, and the page does not suggest otherwise.
