Hello all, I have been cultivating an interest in these one edged daggers from Old Mexico. There have been some great examples found archaeologically, and by accident, and some have survived the years in collections. Does anyone know any good sources of information about these? Aside from references that they are sometimes locally made descendants of Mediterranean dirks, information is hard to find. I would love to see some detailed drawings that illustrate assembly, detail, etc.
I actually first became interested in these because they have been found all over the old Spanish, later Mexican holdings in N. America, and because that includes Texas and Arkansas, some believe that they are a direct ancestor to the Bowie knife, particularly as they have a clipped point.
