Kuhn Rikon 5L which I rarely use, a Kuhn Rikon family cooker 12L which I use most of the time for pressure cooking and a 2.5L pressure frying pan that came with the 5L that I never use. I didn't really understand what I'd use when I bought the first small set, and now would pretty much only use the 12L. Bigger would be nice but impossible to handle for cleaning in my kitchen.
