There are probably more extant than you'd think. My only iron is still a Weller from 1973 - still on its first heater, 'cos I turn it off when not in use. In the last decade I've bought a couple of new tips, including one from Plato, which has a hollow in the angled face. Once filled with molten solder, it allows a dozen pins on one side of a QTFP package to be soldered in one second, after a thin bead of flux has been run first. > OTOH I have a > junk box with at least 2 of the platinum thermisters in it.

A steeper angle would allow more wear to be taken up with less screw turns, but probably increase the chance of it slackening off with vibration.
