One of the few companies left that makes all-metal, high-quality. pull-down kitchen faucets is In2Aqua. You can read more about that in the comments on this rather long thread: https://www.houzz.com/discussions/4847102/in2aqua-kitchen-faucet-vs-brizo-rubinet-california-faucets#n=41

In2A is good, and there are several really great, high quality options as well. Before you choose this type of faucet, think about the way you use your kitchen faucet. Then do a little research. Starcraft Builders has pretty great reviews of different faucet makers. I am currently looking at KWC faucets, and they have a similar option, a little more refined I think, a little less industrial. Either way, it’s a big statement for a faucet. Let us know what you pick!
