Interesting shape of arrowhead. Looks as though it would be easy to shape with a hammer on an anvil. Very simple shape.
Have you ever done any metal forming with a hammer and anvil?
It takes a lot of skill to do something this delicate!
I can do stair rails, spikes, and horseshoes but an arrowhead, NO!
That takes years of experience to get something that small done right.
And its apparent length and narrow width would probably help it really bore through the air and its eventual destination.
