Carving a wax knife would be easier if he knew more about how a knife was supposed to be shaped but there's an outline on the paper labeling the parts of the knife (all of them have names, who knew) and it's small but it doesn't actually say he has to make a large knife, so he can kind of trace that, at least in the one dimension, and then figure it out from there. It's sort of ironic that he's carving the wax knife with the pocketknife he brought in with him, but that's just sort of how it is, he supposes.
