I think with a few frypans, saute and their choice “non-stick” anyone should be all set.
I’m certainly not a one pan does it all type of guy though ;). I just received my 15th frypan last week (24cm de buyer Milady) and its pretty nice. I also ordered a new saucepan yesterday haha, but I was well within my right to do so here, as it was a long handled straight wall stainless saucepan, a first for me.
I like to have a good tool for a given job and because of that some of my pans have ended up having pretty niche uses or have just become second, third, fourth choices, as I like the others better in the most usual cooking tasks.
