I am not @boilsover but that is what I'd call a Windsor pan. One of my most used shapes. Wish I had a copper one. The pan you linked is not on sale...otherwise I would be tempted...except, fortunately, I am broke.
I hear you. I had a reasonable year on my day-job, but the cost on that baby is, well, staggering.
@boilsover, Thanks. It sounds like whatever difference, if any, between the pan Mauviel is designating a "splayed saute pan" and the Windsor/slant-sided sauteuse evasee is insignificant. I appreciate the responses.
