I have been trying to find a sword, dagger, knife, bayonet or any other kind of weapon that would have a blade with fullers on one side and a ridge in the center on the other. If you were to cut the blade in half and look at a cross section, it would look like the double fuller in the attached pic on one side but the other side would be a center ridge. Anyone know what this may be? It would be made somewhere before 1960. Any help would be greatly appreciated.
