When the bowie knife came into vogue in the 1830s, America did not yet have the manufacturing capacity to meet the demand. However, the cutlers of Sheffield, England did, and soon flooded the market with their high quality bowies, available in a dazzling variety of styles. (I have noticed that many internet sources identify the 1850s as the time Sheffield knives were first introduced to the American market. This is incorrect. There were Sheffield imports here in the late 1830s.)
Here is a close-up of a Spanish choil on a knife made by Dean Oliver of Oregon:
The Sheffield knives can be seen and ordered through the website of John Nowill & Sons. Just be sure to tell them you don't want the f---ing filework! (unless you do).
UPDATE: Below is an example of a bowie with extensive filework, for those who don't know what I'm talking about. To me, it looks like it was gnawed by gerbils.
