Feather vs Astra vs Nacet: What's Different and What Isn't

By The HONE Team · September 25, 2026 · 6 min read

Two of these three blades are Gillette brands. All three are the same size and fit the same razors. What separates them is how keenly the edge is ground — and keener isn't better, just keener. Here's what the specs say, and where they stop.

You went looking for a comparison and the internet gave you a ranking. Feather the sharp one. Astra the all-rounder. Nacet the smooth one. Three brands, three personalities, pick your fighter.

It's reasonable to read three different boxes as three different products.

Then you look at who makes them. Astra Superior Platinum is a Gillette brand. So is Nacet — it's sold as Gillette Nacet. Feather is the outsider here, made by Feather Safety Razor. So the three-way comparison is really a two-family comparison, and nobody's top-ten list opens with that.

Start with what's identical.

A double edge blade is a standardized part. The Badger & Blade wiki puts the nominal figures at 43 mm long, 22 mm wide, 0.1 mm thick — and that isn't a Feather figure or a Gillette figure, it's the figure. It's why any of the three drops into any safety razor made in the last century.

So compatibility is not a differentiator. Any page selling you one blade as the right fit for your razor is selling you what the standard already gave you.

All three are stainless, individually wrapped, and arrive with a coated edge.

Then what looks different and isn't.

Here's the part that surprised us. The metal in the name is not the part that touches your face.

Every DE blade starts with a layer of PTFE over the edge. The B&B wiki explains why: a bare stainless edge has microscopic pits and crevices, and PTFE fills them in. The platinum, chromium, iridium or tungsten on the box has a different job. It helps that PTFE stick, and hardens the edge underneath.

Which means "platinum" tells you less than it looks like it does. On the wiki's own list of platinum-coated blades you'll find both Astra Superior Platinum and Feather Hi-Stainless — the two blades the internet treats as opposite ends of the scale.

Same coating family. Reputations at opposite poles. The word on the box is not doing the work.

What actually differs.

One axis, really: how keenly the edge is ground and finished. That's what people are describing when they call Feather sharp and Astra forgiving.

We should be straight about the evidence there. There is no public, comparable sharpness measurement for these three blades. What exists is retailer copy, a very consistent body of forum opinion, and no numbers anybody can check. So we're not going to hand you a ranking dressed up as data.

That last row is worth sitting with, because it's the one everyone gets backwards. Comparing sticker prices across a five-pack, a ten-pack and a hundred-pack tells you about packaging, not about blades. The comparison that does pay is the one against a cartridge, and we already ran that arithmetic: The 5-Year Cost of Shaving: Cartridge vs Safety Razor.

So which one do you buy first.

Nobody can tell you which of these you'll get on with. Not the forums, not the retailers, not us. No test predicts it, because the variable is your beard and your hand.

What you can do is read one shave correctly.

If the shave tugged and you kept going over the same patch, the edge isn't keen enough. If it shaved very close and your neck is sore by evening, it's keener than you need. Those two outcomes point in opposite directions, and one pass tells you which you're in.

Buy a sampler, not a hundred-pack.

Five of each costs less than a sandwich and settles the question in three weeks. Buying a hundred before you know is how drawers fill up with blades nobody likes.

And the people who swear by Feather aren't wrong, by the way. A keen edge on a coarse beard with a light hand is a real result — it just doesn't transfer to a different face. Their answer is an answer to their own beard.

Does the tool actually change this?

What the specs can't tell you.

In 2017 someone on Badger & Blade shaved half his face with a Nacet and half with an Astra SP, same prep, same session, one razor. "the Astra SP, to my surprise, was smoother and more efficient" — and then, tellingly, "you will find it pairs with the Astra SP very well."

Read that second line again. His conclusion wasn't about the blade. It was about the blade in that razor. One man, one face, one session — not a study, and he doesn't pretend otherwise.

That's why this page has no winner at the bottom. The goal isn't the best blade. It's the blade you stop thinking about.

Two things move your results more than brand choice: how long you keep a blade in, and what you do with the razor. Both have a page of their own — How Often Should You Change a Safety Razor Blade? and, for the wider view on choosing, Double Edge Razor Blades: How to Choose One.

Questions people ask.

Are Astra and Nacet the same blade?

No, but they come from the same company — both are Gillette brands. Treat them as two products from one house rather than as rivals from opposite ends of the market.

Is Feather better because it's sharper?

Sharper isn't better, it's sharper. A keen edge suits a coarse beard and a light hand, and punishes pressure. There is no public, comparable sharpness measurement for these three blades.

Does "platinum coated" mean the edge is platinum?

No. Every DE blade has a PTFE layer over the edge, and the metal named on the box is mainly there to help that layer adhere and to harden the edge underneath.

Will any of the three fit my razor?

Yes. Double edge blades are standardized at nominally 43 × 22 × 0.1 mm, so all three fit any standard safety razor.
