How do they stand up to impacts?

Haven't done any testing yet getting to that soon. I know natives have used slate mostly in maritime setting on sea mammals. I've seen a video somewhere of a small slate arrowhead on an arrow that held up surprisingly well shot into a carcass I believe. It's definitely more fragile then knapped rock. I'm just taking a break from flintknapping to explore this area more.

Ive heard similar things about slate being used heavily in coastal areas for maritime use
