I'm on my first playthrough and I'm playing Hunter, so right before it starts I grab a stack of flint, I hide in my cellar, surround myself with dirt leaving only 1 floorspace to work and knap tons of arrowheads. I see almost no reason to use metal arrows, they are too much of a hassle to make.
If it happens while I'm on a mining expedition usually I can use the local stone to knap some spears too, but sadly not the arrowheads.
Another great option in the house is to grab clay and make crocks or storage vessels. You can never have too many of those.
