Including the six-point satisfaction gap, the one kind of beard that defeats a mild razor, and why a hundred blades cost less than a quarter of one replacement head.
Short answer
Safety razors satisfy more of their buyers — 86 to 87 per cent in the four-to-five band against 78 to 81 per cent for the electrics we checked — and cost almost nothing to run, at 8.9 cents a blade. Buy one if irritation is your problem and you shave at a sink. Buy the electric if speed is your problem. Buy neither if your beard is very coarse and you want one pass.
The electric shaver is the default recommendation for men who hate shaving. It is also the format whose buyers are least satisfied.
We read the rating histograms on four listings on 12 September 2026 — two electric shavers, two double-edge safety razors — and the gap is not subtle.
Six to nine points, consistently, in the same direction, on samples from 1,917 to 12,176. The cheaper tool satisfies more of the men who buy it.
That is the finding. What follows is why, who it does not apply to, and the running-cost gap that is much larger than the purchase-price gap.
Why the electric numbers are lower
Electric shavers fail in a specific, repeatable way, and their critical reviewers describe it in almost identical language. A three-star on the Braun from June 2026: “leaves me with bumps, ingrowns, and pulls my hair out”
Foil shavers lift and cut the hair slightly below the skin line on some faces and pull it on others, and which one you get is a property of your face rather than the machine. That is why a $90 shaver draws one-star reviews from men who own the same model that other men rate five stars. There is no adjustment that fixes it.
A safety razor cuts at the skin surface with a rigid blade. It is more mechanically predictable, which shows up as a tighter distribution — but it puts an exposed blade against your face, which is the other half of the story.
Where the safety razor fails instead
Not on nicks, which is what everyone expects. On coarse hair.
The Henson has the highest one-star share of any product here, at 6 per cent, and its three-star reviews say what the one-stars say more politely. From April 2026: “If you have hair strand follicles that are thick and stiff this would not give you a clean shave”
That is a mild-aggression razor doing what a mild razor does. Blade exposure is the variable, and a razor tuned to be forgiving on sensitive skin will not clear dense stubble in one pass. Buyers who wanted both got neither.
So the decision is not really electric versus manual. It is: is your problem irritation, or is your problem density?
The running cost, which is the part nobody prices
One hundred Astra Platinum double-edge blades cost $8.88 — 8.9 cents each, 4.6 stars across 55,487 ratings. Most men get three to five shaves from one.
One genuine Braun Series 5 replacement head costs $37.90.
That is the whole argument, and it does not need an assumed replacement interval to land. A hundred blades is more than a year of shaving for under nine dollars. A single consumable part for the electric costs four times that, and the shaver itself will not outlive the razor — a Merkur is a solid brass tool with no battery in it.
Where the electric wins on cost is time. It needs no water, no lather, no sink, and it is three minutes instead of ten. If you shave in a car park at 8:40am, none of the above matters and you should buy the Braun.
Which one to buy
Buy the safety razor if: you get razor burn or ingrown hairs from cartridges, you shave at a sink with time to do it, you want the running cost near zero, and you are willing to be bad at it for two weeks. Everyone is bad at it for two weeks.
Buy the electric if: you shave in a hurry, you travel constantly, you shave in the car or at a desk, you have a tremor or limited grip, or you keep stubble rather than going bare. Also buy the electric if you have tried a safety razor and hated it — that is a real answer and the satisfaction gap above is an average, not a prediction about you.
Buy neither, for now, if your beard is very coarse and you want one pass and out. A mild safety razor will disappoint you and a mid-range foil shaver will pull. That is the case for an aggressive razor or a rotary shaver, and it is a different page.
If you go the safety-razor route, the two-week thing is real
Angle and pressure are the entire skill and neither is intuitive coming from a cartridge. Almost no pressure, roughly thirty degrees, and short strokes with the grain for the first week. Nearly every one-star review of a double-edge razor is written inside the first fortnight.
Start with a sampler of blades rather than committing to a hundred of one brand. Blade feel varies more between brands than most men expect, and the blade matters as much as the razor.
What we could not check, and why we are saying so
As of 12 September 2026 Amazon no longer allows filtering reviews by star rating. The filters, the histogram links, the aspect chips and the review-page numbers all return the same small default sample, which skews positive. So the distributions on this page come from each listing’s own rating histogram, which is complete, and the quotes come from the reviews Amazon actually served, each logged against its ASIN. We have not counted the critical reviews ourselves, and we are not going to imply otherwise.
Questions men actually ask
Is a safety razor better than an electric shaver?
For most buyers, on the evidence, yes — the two safety razors we checked satisfy 86 to 87 per cent of raters against 78 to 81 per cent for the two electrics, and they cost almost nothing to run. That is an average across thousands of people, not a prediction about your face. If you shave in a hurry or away from a sink, the electric is the better tool for your life regardless of the distribution.
Do safety razors give a closer shave?
Usually, because the blade meets the skin directly rather than through a foil. The trade is that a mild razor may not clear coarse stubble in a single pass — that complaint shows up explicitly in the Henson’s critical reviews. Aggressive razors close that gap and raise the nick risk while doing it.
How much does it cost to run a safety razor?
About nine cents a blade at current prices — 100 Astra Platinum blades were $8.88 on 12 September 2026 — and three to five shaves per blade. The razor itself is a one-off purchase with no battery and no parts that wear out. A genuine Braun Series 5 replacement head, by comparison, is $37.90.
Will a safety razor cut me?
More than a cartridge will, in the first two weeks, and considerably less after that. Angle and pressure are the whole skill: almost no pressure, roughly thirty degrees, short strokes with the grain to start. A mild razor like the Henson is deliberately built to make those mistakes survivable.
Which is better for ingrown hairs and razor burn?
Most men who switch because of irritation report improvement, and it is the commonest reason for switching. The mechanism is fewer blades and less skin-stretching, so the hair is cut at the surface rather than below it. It is not universal — some men get irritation from a double-edge too — and a recurring folliculitis is a doctor question rather than a razor question.
Can I use an electric shaver in the shower?
Both electrics on this page are wet and dry rated, and the Panasonic’s own reviewers repeatedly say it performs better wet with lather than dry. Check the rating on any specific model before taking it into water; not every electric shaver is sealed.
