Why is obsidian used for so many weapons even though it is very fragile?

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.

It’s incredibly easy to work with no industrialization of any kind. Metal requires smelting and forging. Stone requires time consuming grinding. Obsidian flakes off with a quick strike of a rock or antler.

Additionally, it’s convenient. You can haul around a chunk and flake off bits as needed for arrows, a quick knife, chisel, etc. This also means you can repair your club-sword after battle!
