Some raw material has fallen into my hands and I'd like to explore traditional awl forms.
I'm vaguely aware of birdcage, brad, marking and piercing and have many questions.

For instance: marking and piercing awl tips look identical; are there differences?
Also, do birdcage awls with differently tapered facets have different uses?
And so much more...

If anyone has leads on source material or direct experience I'd appreciate being pointed in the right directions.
