d-2, you have reference to James Black and it is probable that James Bowie had a knife or two made by this smith, although we have no proof of that fact, AFAIK. The romantic version in "The Iron Mistress" is just that, a romantic tale for a movie. What needs to be remembered is that both Bowie brothers, James and Rezin, were "knife knuts" as well as knife users of some considerable skill and, as such, likely had more than one knife that they carried around. How many of us "knife knuts" in this forum stopped with one knife? Think about it. They also were both in the habit of giving knives to friends and business acquaintances, apparently. So there are probably any number of knives floating around out there that really did belong to one or the other Bowie at one time. But nobody has come up with evidence to support such a claim other than one or two that Rezin gave to people, such as the Daniel Searles knife in the Alamo Museum.
