I’ve been coming across videos of people breaking obsidian chunks to make arrowheads but could never find the answer why it could be broken with light hits with a rock, and then not break when in use with said weapon.
No one is making swords out of obsidian or even spear tips. They’re making arrowheads out of obsidian because it can be made insanely sharp with very little work. What does it matter if an arrowhead shatters after it penetrates 4″ into your victim’s chest?
