What happened to Medyna Rasierklingenfabrik GmbH?
Didn't they make all the ice tempered blades, like Souplex, VDH, Timor etc. (cold rerolled strip steel) The website seems have have closed and Google maps doesn't have a name on the factory.
Medyna Rasierklingenfabrik GmbH has been formally declared insolvent on June 17, 2021 by the District Court of Wuppertal (DE). There have not been any updates since then so probably the company has filed for bankruptcy and closed its operations.

I am not sure about Souplex, but VDH Ice Tempered and Timor are made by Giesen and Forsthoff. Timor is Giesen and Forsthoff's OEM brand.

All private label European blades are made in their facility, the Czech Blades facility, and Edgewell's Wilkinson Sword Solingen facility.

The Czech blades are easy to identify because they are thin, light, laser printed, and have poor durability and consistency.

The German blades can usually be identified by the proprietary plastic tucks of each facility, different wear curves, and the dates stamped on the Edgewell ones. The new Muehle has its own paper tuck, but has the other distinguishing traits of a Giesen and Forsthoff blade, including matching performance of the one in a distinctive Giesen and Forsthoff plastic tuck.

All of the German blades are marked 'Germany' and never 'EU' or 'Europe.' Some German branded Czech Blades will say 'Germany,' or 'Solingen,' but unlike real German blades, they will also mention 'EU,' 'Europe,' or 'cz' somewhere.

Of course there are older blades from closed facilities that can still require some detective work.
 
That's a shame. Quite recent then, that would explain Merkurs and others move to Czech blades maybe?
Latest German Merkur blades were produced by Feintechnik. At a certain point in time many brands who were sourcing OEM razor blades from Feintechnik changed their provider. Bolzano and Elios, for example, have turned to Sotraco in Egypt while Merkur chose Tatra in Czech Republic. Obviously they weren't after quality rather they were on a quest to find the cheapest blade available.
Dovo, who now controls Merkur, has their razor blades still made in Solingen, Germany. Current Dovos are the old German Merkurs rebranded.
 
AI generated? Me thinks the LLM was on LSD
The 'AI' image generators have a rough time with text; it's a whole different challenge. There is work on this front, but getting meaningful - heck, even just readable - text is not assured when working with stock generators.

I'm actually surprized helicopter got such a good result as he did with out expert-level (->100s and 100s of hours) experience.
 
I used one out of the packs I bought (because of you) and they seem to be the same as all my other older Lab Blues.
My personal jury is still out on the Accutec PCC/Lab Blues .. nevertheless, I just picked up five more cartons from an online barber supply store "on sale" for $13/100. I tried to get six, but it wouldn't add it to the cart, so I dropped back to five and badaboom, it worked. So apparently I cleaned them out.

They also had a good price on the Feather Professional AC blades, which are clearly still in regular production, but I grabbed two of those while I was at it (even tho I'd already made the shipping minimum).

@pjgh As far as I understand (but I have no manufacturer verification), Treet Carbon Steel (the blades literally called 'Treet Carbon Steel', specifically - the 'Black Beauty' ones) and Treet New Edge do not have a PTFE coating.

According to the data in this thread, the Treet New Edge are sharper. I am currently using Treet New Edge. I disagree about 'unusably rough'. Maybe that applies to the 'Black Beauties', but I wouldn't say it does to the New Edge*. Rougher than other blades out there? Yes. But then I've tried blades with a PTFE coating that didn't seem very nice. Arguably, isn't the grind just as, or more, important?

Either way, I want to use blades without PTFE, and buying ones without is the only way to change the market, as far as I'm concerned. My technique and razor will have to compensate for any deficiencies of the blade. If these Super Powers (likely) don't have a PTFE coating - in the estimation of the OP, I mean - they could be a winner, as it will avoid the rust that is possible with the Carbon Steels ('Black Beauties') and New Edges, and, according to the testing, they are sharper than the New Edges, which would be perfect for me.

*To be fair, it's difficult for me to make a fair (even in a subjective context) comparison between the Black Beauties and the New Edge as I haven't used the Black Beauties in my current razor, which I've used the New Edges in, and I could be biased by the data I've seen on this thread (psychologically).
I’ve been using Treet new edge and have been very impressed. They are sharp and smooth on my face. Ive used about 4 different blades. This one is on shave 4. The down side is having to deal with the blade in between shaves of course. I find these nothing like black beauties that I’ve found pretty much a rough experience.

What I've found with Black Beauties is that some are rough and some aren't. And it's not a razor compatibility issue,
it'll happen with the same razor!
I've been using Treet Platinum's for a couple of weeks now and they're A-1!!
 
@helicopter Do you know anything about these Chinese Rhino blades?

I really enjoy these whenever I use one ... lucky to have a modest stash.

Several years ago, there was a reasonable weight of evidence to point at Gillette Shanghai but the internet has forgotten most of it and what's left looks sketchy.
I have not been able to get that Rhino or Force. Until the early 2000s, Shanghai Cloud produced blades for Gillette under contract. After that, around the time Procter and Gamble took over Gillette (2005), production was fully moved to Shanghai Gillette, which had started production previously in the early 90s.
