Looking at that can (Carnation condensed milk), I doubt that any
similar can opener can actually open them reliably.

Wait... 'evaporated milk' has the oddball cans with almost no lip. The
condensed milk (sweetened condensed milk) has a pretty normal can with a
substantial ring at the top, and can be properly opened with a rotary can
opener.

I remember the no-lip cans, but I have Carnation cans of both
evaporated and condensed in the cupboard, and I see that they both
have lips. But the lips are thin and a little shallow.

Again, "just punch two holes in the son-of-a-bitch." g (As if there
should be any question, that was not a real ad jingle.)

But to your general question -- lips on metal cans have gotten thinner
over the decades. Only pretty-good rotary can openers can get a grip on
most of them.
