Pure speculation on my part, and I’m curious to follow your AA story

Yeah, I thought of that too. Normally, that wears away after the first few days, though. (Among the many useful takeaways I’ve had from previous AAs 🙂)

I must have missed our forgotten the evidence of that. Is the sputtered metal (and its removal) visible under your microscope?
gcgallant@sub.wetshaving.social 1 month ago
Yes. It’s generally gone within the first few days. I think, now, that the added comfort of the sputtered material comes from reducing the harshness of a freshly machined edge.

I’m a bit confused here. My understanding is that the polymer coating is here to increase glide and reduce the harshness. The sputtered tungsten, titanium and whatnot is sputtered onto the edge, under the coating to add wear resistance, but it makes the surface rougher, which I thinkshould translate into a harsher feel.
