This is a blade (not sure that’s the right terminology) from inside a GE90 engine.
It’s totally real except the silver part is paint instead of titanium, which is what it has when it’s actually in an engine. As I understand it, the titanium leading edge protects the composite materials that make up the rest of the blade from impacts.
Mostly, though, I just think “titanium leading edge” would make a good name for a band. (Would be funny to combine with Wikipedia names your band.)
