Many people seem to prefer a blade after the coating has worn off (after maybe 1 or 2 shaves). So why don't said people just buy uncoated blades?
Astra SS coating is listed as...stainless steel.I wonder if some coatings just bother my skin. I love Astra SS. SP, not so smooth.
Well I'll be!Astra SS coating is listed as...stainless steel.
I'm no expert, & I didn't sleep at a Holiday Inn last night either. But I think the above explanation makes sense to me, & that's how I've reasoned it out in my mind. The coating needs to wear down a bit to smooth the blade out. The coating is still there, as that's what gives some of the blades such great longevity.I don’t think the coating on the blades wears completely ‘off’. I think it wears ‘down’ and still creates a buffer into places in the steel that are irregular. My theory is that it is that excess coating that we dislike on initial shaves but the coating that sticks past that does help.
Blades without a coat are cold.Many people seem to prefer a blade after the coating has worn off (after maybe 1 or 2 shaves). So why don't said people just buy uncoated blades?

The polymer coating spills over the edge of the blade during the spray application on the bevels and is then baked on. It is the overspray on the edge that wears away after a few strokes that exposes the true blade edges; hence the percieved implication that the blade gets sharper after initial use. The polymer on the bevels enhances the smoothness and lasts a lot longer than people think.Many people seem to prefer a blade after the coating has worn off (after maybe 1 or 2 shaves).

The issue is the effect of the coating on the tip of the cutting edge where it can cause some initial roughness. From what I've seen in some of the blade coating patent applications the benefit of the coating often comes in reducing friction thereby allowing the blade to pass through the hairs more easily after they have been cut. As a result the once the initial roughness is past the blade delivers a smoother and more comfortable shave. Additionally the coatings may help retard rust formation on our blades.Many people seem to prefer a blade after the coating has worn off (after maybe 1 or 2 shaves).

I am the opposite. Love SP, have never gotten a comfortable shave with SSI wonder if some coatings just bother my skin. I love Astra SS. SP, not so smooth.

Interestingly enough, I just binned my latest light blue Gillette Platinum after 7....
A Gillette Platinum can give me 7 shaves out of which five are excellent and two are decent. A Gillette 365 can give me 3 shaves, two of which are excellent, at best, but more often than not I get three shaves with irritation.

Do you mean this in the sense that the manufacturer actually applies some form of chromium oxide to the blade? My understanding was that the chromium in stainless steel oxidizes itself to form a "stainless" surface layer (or acid is used to bring this out and eliminate iron that would rust on the surface).Uncoated stainless is still coated. It is coated with chromium oxide.
