The classic pointed pen calligraphy nibs from the golden age... do check out the book An Elegant Hand, by William Henning! - those were steel nibs. They were all dip pen nibs though. You can still get steel dip pen nibs with lots of flex.
Noodler makes a pen with a flex steel nib. I haven't tried it though.
