I woud like to carve stuff!
You coud carve something like arrowheads, spears, or even tool / weapon handles (eventually completely custom)
I think it woud be very cool to sit at a campfire with your friend, and just cook your meet, carve new arrows or build a new weapon from found scrap on your journey.
well there is already kind of carving at the woodworking station, there are chisels and you place in 6+ pieces of logs in the machine to get started, add your page from the book to the little metal square thing on the left and chisel out the pieces that glow with a hammer and chisel. but a crude portable version would be quite nice
