Lloyd, those two Robesons are very nice.
Robeson made that NO-RUSTAIN swing-guard hunter with a spear blade, as well. I've never seen a complete example, but own two, both with missing guards and well used.
The Wood Craft knife also was produced as a two bladed knife, the clip and the gouge or chisel.
Roland, here is another four blade sleeveboard from Robeson, though not nearly so elegant as that shown by Joe above.
