I have a really eclectic collection of mostly rather old cookware that still works great. I have a set of two pressure cookers from Kuhn-Rikon, made in Switzerland. There's a large stainless steel pressure cooker made of very heavy South Korean stainless steel (mostly used for soups and stocks). Most of the rest is old cast iron pieces from American companies like Lodge and Griswold. I have a cast iron wok. Also a couple of heavy clad stainless steel pieces I inherited from my Mom that are probably 50 years old or so.
