I believe they were made as fakes, that is "meant to deceive". There are many many different styles and brands out there, the bowie knife market was inundated with fakes from England in the 1970s and 80s, and there are likely some faked here in the USA. Once a type or brand of knife goes way up in value the fakers can't resist a chance for easy money. Every one of those silly "Wells Fargo mail knives" and KKK bowies are ridiculous fakes likely exported to the USA by Dean & Adams, a company that was also behind the plethora of fake Tiffany belt buckles that came on the US market in the 1970s. Thousands of buyers were duped by the Tiffany buckles, and many have been duped by the fake bowies.
