Urban 'flint knapping' arrow heads.

[Scythe13]

I think Steve was going along the lines of, there are better ways to make them, e.g. filed metal, blacksmithing, or something like that.

He's probably right that it's an antiquated skill, and there are many better options. But this is a cool fun way to do it, and the end result is still an arrow head (even though it'll be a single use head, if you miss the target, or hit a bone). But the fact still remains that you can still learn this skill, and if intend to use a bow and arrow, then this is a valid way to make effective heads.
