Presumably also the Numenoreans had it. The description of latter-day Numenor reads like they were technologically very advanced. The question is how far, but it seems fair to assume there was a sharp drop after the Fall because of the colonies not being self-sufficient enough to maintain their tech level. If we consider the stories in the Silmarillon to be handed down orally, the most advanced technologies could have simply been left out or summarized as "magic". No point detailing them if there's nothing in the daily lives of your audience that is comparable.
