If you have a bit of outside space flintknapping is a fairly accessible and very fun hobby, there are good YouTube tutorials and websites that sell the rocks and tools you need (other rocks, antler, leather, optionally copper). I recommend starting with obsidian or dacite, they are much easier than flint and chert. I wear glasses but if you don't I would also get safety glasses and optionally safety gloves. You will cut yourself if you don't but they're almost all very clean cuts that heal fast.
