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.
Would either of the arrowheads below take more or less skill?
Medieval arrowhead about 1200 AD.
Recently found arrow (with head) about 700 AD.
I believe skill levels of craftsmen remain about the same, but technology changes over time.
