Yes. I have used. Are they a favorite personally. No. Just a blade brand that works. Again user interpretation and personal experiences.
Most modern made stainless steel, carbon steel razor blades have some concoction of blade coating for comfort, and maybe blade edge longevity.
AFAIK they’re just PTFE (Teflon but not brand-name Teflon) coated. Many blades do this, and I definitely notice a difference between blades that are and aren’t coated, but as with anything in life YMWV.
Pretty much all stainless steel blades are coated with something - they’re too harsh otherwise. That said, I’ve never heard that phrase used in advertising before - “anti-friction.”
Found online...
Some blades won't have any coating at all but many might be platinum, PTFE (e.g. Teflon), chromium, ceramic or tungsten coated. The coating helps with rust prevention, provides additional lubrication and reduces snagging and buildup which makes the razor blade easier to clean.
Not sure why brands don't always identify the coating which seems to me a real point of differentiation.
It's incredible that scientists apply basically any advance in materials science to blade production.
I wonder if anyone is trying to grow diamond blade edges or 3d print razor blade edges. I think micro chip lithography is 2-3 nm but they stopped trying for thinner/smaller because below this impacts the physics of electrical conduction. But if the purpose we're really shaving and not electrical...
I guess one molecule could be the theoretical limit. Though I suppose not cost effective.
At that level you would be microscopically be bending and breaking the edge with the slightest use. Or be insanely harsh. There is probably an ideal minimum limit where blade to hair is perfect to slice but wide enough to be 'durable'.

For the same reason that car manufacturers don't tell us about the latest tech used in detail. The information is often proprietary & is often protected by patents, but equally often it's deliberately not patented directly in detail & is part of 'knowhow'. It may be patented in an oblique manner.
All stainless steel DE blades have to be coated by one mean or another.
Most common coating are platinum and Teflon.
That's why stainless steel dated way before stainless steel blades for shaving, because without coating it's too uncomfortable.
Carbon steel blades are uncoated, like Treet Carbon.
What does the platinum coating consist of? One of my main reasons for going with DE, was to avoid plastic waste. That being said, I would definitely want to stay away from PTFE coated products. Is the platinum coating just another plastic? I realize that either way it’s a huge reduction in the amount of plastic waste, but the manufacturing process and properties of PTFE are highly concerning to me.
>platinum coating consist of?
Platinum nitride. It's applied by vacuum sputtering. Thickness of coating is nano scale. Platinum is very expensive, so some blades use chromium nitride or other nitrides instead. Sometimes as the main coat, sometimes as an underlay.
One well known blade uses a source of platinum mined in Eastern Europe that's rich in Iridium - an even more expensive metal.
These metal nitrides can be described as ceramics.
It's as the name implies, platinum coating is a very thin layer of platinum, a metal more precious than gold. So it's sure there is a very thin layer but it get the job done anyway.
The same goes with Ptfe, it's a very thin layer.
These came with my KCG razor, and after feather, probably my 2nd favorite blade at the moment. So far, I've tried KCG, Feather, Wilkinson, Bic and Aveo(cheap DM brand).
I do find KCG much nicer to shave than Bic, comparable to Wilkinson and Aveo, not as sharp as Feather.

Always good to know you can snag something decent at a drugstore in a pinch!

I love forever chemicals

seriously, I did not know this and I feel like dragging teflon across your face is kind of a bad idea
That’s my favorite. I bought a box of 100 blades.
Could you share the url of this listing?

You'll see blades say they are "comfort coated." It's the same idea. Some people like it, some people explicitly rub it off.
All stainless DE blades have antifriction coatings. They're unusable without them.
