*Attach a shaft to the shovel blade
This should be enough to get you going. You will need to get more iron rock for a [[pickaxe ]] and [[hatchet]], but now you can use the carving knife to make shafts, and the shovel to cut down trees (tip: only cut down mature trees, or fruit trees, you need a hatched to chop up felled trees)
Good luck in the lands of Wurm!
