My impression is that bronze production was heavily reliant on long trade-routes because although copper could be found all over the place, tin was only found in a few places. There is also arsenic bronze, arsenic often being coincident with copper with is convenient for making bronze without extensive trade routes, but regardless my impression is that Bronze Age and trade routes go hand-in-hand. For me, the dagger is most impressive because it would have required extraordinary craftmanship to pull off; meteoric iron is much trickier to work than normal iron, particularly if you can't get it up to welding temperatures. From what I've seen in videos of people today trying to work with it, it has a tendency to split apart and crumble when hammered, so smaller pieces are much easier to produce than large pieces. And for an ironworker to be experienced enough to create that dagger, suggests there were a lot more meteoric iron artifacts being made. It was probably an artisan's masterpiece, but there must have been many more works that preceded it.
