More than spearpoints and harpoons, the Tlingit supposedly forged this "Killer Whale" dagger (really more a short sword) out of meteorite back in the 17 century. That's certainly not pre-iron age for much of the world, but pretty advanced technology for these northern tribes way back then.
That said i must say that i am really not completely convinced that the method with which the King Tut dagger was determined to be made from meteorite is 100% fool proof. The make-up of this blade is still all of elements that can be found terrestrially. That it is similar to the make-up of know meteoric blades makes this more a maybe for me than a sure thing.
