Do you mean just the edge? Because with a sword basically the whole thing other than the handle is the blade.
But yeah, with a tiny diamond edge you’d probably have the best of both worlds, a light, flexible sword with an ultra-sharp cutting edge.
Still, the edge probably wouldn’t last for long. If the diamond was attached to a steel blade and the blade flexed, the diamond couldn’t flex and would probably snap.
