I am currently playing as a neolithic hunter in the far north east, using only stone tools. It looks like despite my 98% hideworking skill, the best I can get is a harsh fur or leather.
I understand that the stone knife and axe are supposed to be used in only the most desperate situations; but it would be nice to see them upgraded, or even a "knapped stone" version of each - much harder to make but almost as good as their metal counterparts.
Here's a recent paper on stone tools in neolithic Finland, if anyone is interested!

I admit to not having done the sums, but it seems a stone knife gets you less than a quarter of the yield you get with metal knives. Make the stone knife butchery yield less and take longer, yes - but surely not by such a drastic amount?
EDIT 2: The disparity is even more pronounced chopping firewood with a stone axe. With Timbercraft skill at 92%, it takes over eight hours to make around 22 firewood from a block.
