Henson AL13 vs Merkur 34C
These two razors disagree about what stops you pressing. Merkur says weight. Henson says geometry, and publishes the tolerance to back it.

The short answer
Buy the Merkur 34C if you want one razor and no thinking. 68 grams of chrome-plated brass, a plain closed comb, decades in production and blades everywhere. Buy the Henson AL13 if razor burn is your actual problem. Henson publishes what almost nobody publishes - a blade angle fixed at 30 degrees and machining to as tight as 12.7 micrometers - and at 37 grams it asks you to stop leaning on the razor entirely.

The disagreement in one line
Both razors are trying to stop you pressing, because pressure is what causes razor burn, weepers and a sore neck. They disagree completely about how.
Merkur's answer is mass. Sixty-eight grams of chrome-plated brass sits on your face heavily enough that pushing feels unnecessary, and the technique follows from the weight.
Henson's answer is geometry. The head holds the blade at a published 30 degrees and exposes so little of it that pressing achieves nothing, and the razor is built light - 37 grams - because the mass is not doing the work.

Where the Henson wins
- Disclosure. A published blade angle and a published machining tolerance are more than any other razor in this ledger gives you.
- Skin that reacts. Minimal blade exposure is the mechanical reason people report less irritation, and it is the reason to pay the premium.
- Travel. At 37 grams it is the lightest razor here by a wide margin.
- It cannot be set wrong. There is no plate to choose and no angle to find - you ride the head flat against the skin and the geometry does the rest.
Where the Merkur wins
- Price. It is a fraction of the Henson and it has been the default recommendation in this format for years.
- The weight teaches you. For somebody arriving from a cartridge razor, heavy is a useful instructor - you feel immediately when you are pushing.
- Availability. Made in Solingen and stocked everywhere, with parts and advice equally everywhere.
- Nothing to learn beyond the angle. Two pieces, a plain closed comb, no settings.
The honest cons, both ways
Henson: aluminum will never feel like the heirloom object a brass or stainless razor does, the price is several times the Merkur's, and the published tolerance is a manufacturing claim you are taking on trust rather than something you can verify at the sink.
Merkur: the short handle suits medium and small hands and frustrates large ones - the Edwin Jagger comparison is specifically about that - and Merkur publishes almost nothing beyond weight and material.
The verdict
Most people: the Merkur 34C. Cheaper, heavier, universally stocked, and the weight does the teaching. If you are leaving cartridges and want one razor for the next twenty years, this is still the answer.
If your skin is the reason you are shopping: the Henson AL13. You are buying published geometry rather than published mass, and on a neck that breaks out after every shave that is the more useful thing to buy.
Either way the blade matters more than the razor on any given morning - matching a blade to your skin is the cheapest variable to change.
Every pick, with the working
Each entry shows the published specifications, the axis scores they produce and what you give up. The order is the computed order, not a commercial one, and the arithmetic is open underneath every score.
Our pickThe lightest touch, machined to spec
Henson AL13 Medium
Henson's argument is that razor burn is an engineering problem, and it publishes the tolerances to back it: blade angle fixed at 30 degrees, machined to as tight as 12.7 micrometers at an aerospace facility in Ontario. At 37 grams it is by far the lightest razor here, which inverts the usual advice — you cannot let this one do the work, you have to let it float.
- Weight
- 37 g
- Length
- Not published
- Material
- Aircraft aluminum, Type II anodized
- Head
- Fixed exposure, 30-degree blade angle
- Blade gap
- Machined to as tight as 12.7 micrometers; exposure fixed by model
- Blades in the box
- 5
- Made in
- Canada (Ontario)
- Refill
- Universal standard
- Warranty
- Not published
- Assumed service life
- 5,200 uses
The arithmetic: 260 shaves a year x 20 years of assumed service life = 5200 shaves.
What it gets right
- Published machining tolerance of 12.7 micrometers and a fixed 30-degree blade angle, which nobody else in this ledger discloses
- 37 g aluminum body with a Type II anodized finish; nothing to chip or peel
- Five blades in the box
- Sold in Mild, Medium and Aggressive so the choice is made once, at purchase, rather than every morning
Flaws
- 37 g is very light, which removes the weight cue a cartridge user relies on
- The exposure level is fixed at purchase; changing your mind means another razor
- Aluminum will not feel like the heirloom object a stainless razor does
The working behind the 8.5
- 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
- Fixed geometry with a published 30-degree blade angle removes the angle guesswork (+), blades included (+), but 37 g is the lightest here and the razor's own mass supplies almost none of the pressure (-).
- Refill economics: 10.0
- The refill is a commodity standard that dozens of factories make, so the price is set by competition and no single maker can raise it.
- What the maker publishes: 8.6
- 6 of 7 specifications a buyer would expect are published: weightG, material, madeIn, headType, bladeGapNote, bladesIncluded. Not published: lengthMm. 6 / 7 x 10 = 8.6.
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 Henson AL13 published specifications.
2One razor, no research
Merkur 34C HD
Buy this one if you want to stop reading and start shaving. It is 68 grams of chrome-plated brass on a short knurled handle, which is heavy enough that you naturally stop pressing, and the head is a plain closed comb with nothing to set, adjust or get wrong. It has been in production in Solingen for decades, so parts, advice and blades are everywhere.
- Weight

- Refill
- Universal standard
- Warranty
- Not published
- Assumed service life
- 5,200 uses
The arithmetic: 260 shaves a year x 20 years of assumed service life = 5200 shaves.
What it gets right
- 68 g in a 80 mm body: the weight does the work, which is exactly the habit a cartridge user has to unlearn
- Closed comb with no adjustment, so there is one variable fewer on your first month
- Two-piece construction; the head unscrews as a unit and there is nothing to lose in the sink
- Takes any standard double-edge blade, so the refill is a commodity
Flaws
- The 80 mm handle is short for large hands, and Merkur's own longer handles are a separate purchase
- No blade in the box, so the first order needs a blade pack alongside it
- Chrome over brass will show wear at the edges over years in a way stainless will not
The working behind the 8.9
- 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: 8.5
- Closed comb (+), no adjustment to set (+), 68 g published weight in the range where the razor's own mass supplies the pressure (+), no blade included so the first order is two items (-).
- Refill economics: 10.0
- The refill is a commodity standard that dozens of factories make, so the price is set by competition and no single maker can raise it.
- What the maker publishes: 8.6
- 6 of 7 specifications a buyer would expect are published: weightG, lengthMm, material, madeIn, headType, bladesIncluded. Not published: bladeGapNote. 6 / 7 x 10 = 8.6.
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 Merkur 34C HD listed specifications (Fendrihan).

Questions people actually ask
Is a lighter razor harder to use?
It changes the technique rather than the difficulty. A heavy razor does the work if you let it rest on your face; a light one needs you to guide it without pushing. Both are learnable, and pressing is the mistake either way.
Does the published blade angle matter?
It is the specification this category hides most. Henson fixes the angle at 30 degrees and machines the head to a published tolerance, which is an engineering answer to razor burn rather than a claim about it. The razor burn guide covers why angle and pressure do the damage.
Do they take the same blades?
Yes. Both take any standard double-edge blade, which is the entire economic argument for this format - the blade roundup covers the field and the calculator does the arithmetic.
Which is more aggressive?
Neither publishes a blade gap, so the honest answer is that we cannot compare them on the number that decides it. Henson sells the AL13 in mild and medium variants and publishes the angle instead; Merkur publishes neither.
Which lasts longer?
Both should outlive you. Chrome-plated brass and machined aluminum are both maintenance-free if you dry them - and neither maker publishes a warranty, which is standard for this category.
Which for a first safety razor?
The Merkur, for most people: it is cheaper, the weight teaches you not to press, and it is the most widely stocked razor in the format. The beginner roundup covers the full case.
