Pen recommendation - non plastic

Currently my main pen is a cheap and simple Lamy Safari. I have other fountain pens but this one is just what I keep getting back to. The other ones I have are not very expensive either.

Now I want to get something nicer, that writes well and that isn´t plastic. I was looking at some reviews of Kaweco Sport it brass or aluminum, but they seem to be on the smaller side and the design doesn´t really appeal to me.

What other non-plastic fountain pens can you recommend that are high quality and writes well?
