It's why I bought 100 Bruce Lee blades. The fact that they are good was almost immaterial.

I don't have a funny description.
Because when I think of a sharp blade slicing whiskers off of my face, I immediately think of Mammoths...
I'll take it.
If they're trying to be deceptive, they're not trying very hard. I don't know how many people would be fooled by the generic-looking "American" branding when the country-of-origin (and even the company behind it) labeling is large and prominent.
I'm more surprised that a blade maker would want to be seen as from the U.S. It's not a country known for producing razor blades. As far as I know, there's only one blade maker in the U.S. and they are in the witness protection program to ensure no one learns their name or the name of their products.

Yeah, Accutec really missed the mark with the pricing of their OEM branded blades. They can't just sell blades to Edgewell's Fromm to market under their established Personna brand at $.17 and then turn around and get $.36 for OEM branded blades in a brown cardboard 250 blade bulk pack.
If they put them in a 100 blade box and get the wholesale price so retailers sell it around $15, then they can actually sell some blades through normal retail channels.
And if they want so much to focus on industrial, scientific, and medical, then why sell blades to Fromm cheap and why even have the 250 blade bulk packs?
I believe that Personna is the true heir to the Bergman movie "Persona" and it exists to subvert the very idea of identity.
I bet it’s extinct.
So, was the greif… good? I’ll see myself out…

It was smooth and comfortable, but it broke in my razor like the first test sample.So, was the greif… good? I’ll see myself out…
I guess you win the toughest whiskers contest.
You seen these @helicopter?
Sold by Connaught (UK) ... not sure if it's okay to link direct, but folks can find them
... as if Personna was not complex enough, now Edgewell are making AccuForge! I questioned the proprietor on this and he is absolutely firm that these are made in Germany by Edgewell. I guess it's this SKU https://accuteccompany.com/s/product/accuforge-double-edge-blade-with-microcoat/01t3i0000089qvIAAQ ... but made under license.

Well there goes my understanding of the name change.

This is the KRWN Super Stainless blade, which is the private label blade of a Quebec barbershop company of the same name. It was generously provided for testing by @GeorgeGlass and forwarded to me by @dmshaver I am not sure who manufactures it, or where it is made, but it looks like it is probably Chinese. It is made from soft 100 micron steel with a dull traditional grind and a typical metallic coating. Annoyingly, it incorrectly uses the 'Super Stainless' description indicating a lack of a metallic coating. I bet whoever came up with the marketing material wasn't even knowledgeable enough to get that right. Balance and durability are fair. Consistency is fairly good through the first paper cut, before the steel fails.
It comes in 5 blade tucks with a full flap.
The grind is crude, with coarse and uneven scratches, including a fairly coarse polish on the tertiary bevel. There are visible metallic and polymer coatings. In the second picture, taken after the test, we see that the metallic coating persists to an extent, and that the failure mode of the steel is lots of medium denting, which is something we see with cheaper steels, and improperly heat treated steels. Softer steel is sometimes associated with a subjective feeling of smoothness.
It is a dull blade.
I got a milligram scale and started measuring the mass of each blade. I don't know how I overlooked this data point for so long, but we have it now.

This is the Gocelle New Super Blue Stainless Platinum blade. It is made in China for the Chinese market. The graphic design and branding are designed to confuse Chinese consumers and make them mistake it for a Gillette Super Blue blade, which is a premium blade in the Chinese market.
I am not sure who manufactures it. It is made from 100 micron steel with a dull traditional grind and a platinum driven metallic coating. Balance, durability, and consistency are fair.
The grind is crude, with coarse and uneven scratches and uneven transitions. In the second picture, taken after the test, we see that the failure mode of the steel is lots of medium chipping, typical or low grade razor blade steels.
It is essentially a counterfeit blade, and it certainly violates Procter and Gamble trademarks. Performance is poor, and I guess that's what you get for buying this if you are familiar with the Latin alphabet. Performance and grind are pretty similar to the stainless Flying Eagle of questionable authenticity, close enough that this could be the same blade with an added metallic coating. However, the packaging doesn't match. Still, it wouldn't surprise me a bit if they both come from the same producer. In any case, if you want a Chinese blade of questionable intellectual property usage, go for Cloud Bruce Lee.

I wouldn't say it's necessarily counterfeit!
Counterfeit is usually an exact copy with the same name and everything.
Here they just made a product that strongly resembles another one.
I just compared your picture to a pack of real Gillette Blue Blades and they're different enough I guess.
Nevertheless, I'd never buy them!

I agree it isn't a straight counterfeit. That is why I characterized it as 'essentially' counterfeit.I wouldn't say it's necessarily counterfeit!

Imagine if you were trying to buy an expensive blade that had Chinese writing on it, and someone swapped out the characters for different, but similar looking ones. There is no question it is intentionally deceptive, and no question about whether it violates trademarks from a US standpoint.
Gocelle: The best a mell can gell
Absolutely!
I guess if someone doesn't know and they weren't familiar with the guys head on the Gillette pack it would make them think otherwise.
