Although not "rustic" looking, this manually operated, human powered splitter is awesome for getting those small sticks of wood that are so useful in getting the fire nice and hot. Its basically like a 10 ton jack on its side...
Plus, a Viking like you oughta be right at home with the lever arms --- it feels like you are cross-country skiing while splitting your logs!!
I bought mine for $78 on sale at Harbor Freight. Doesnt take up much room and stands on end when not in use. Handles come off for easier storage.
