I can't answer this poll.
I'll use a stone ax until i have 3 in sex rex and a supply of coffee.
If i am not investing in strength, i'll use the stone axe until i get an auger. Other games, i'll move on to iron by the end of week 1 and steel asap.
With tools, i use whatever means i am not standing around waiting for stamina to regen, which varies game by game.
