Thanks for the information, Mark.
Here's a picture of the actual knife, a close-up of the forge, and the scene from the opposite side (note the leaf-bladed sword):
This knife was a perfect match for the larger sword, so I had Jose restore it in the same way. The similarities between these two, as well as some others in my collection and several others I've handled and looked in photos leads me to believe they all come from the same maker or facility.
