The first problem you will have is with defining what a "bowie" knife actually is...there are rather a lot of interpretations! LOL
Might you not find something on the British Blades makers sales section?
Big question is what do you want it for? There are bowies with long skinny points, straight clips, swepped clips, short bellies and long, hollow, flat and convex grinds, double guards, single guards, no guards and sub-hilts. Prices run from dirt cheap to stratospheric.
The Falkniven A1 could be termed a bowie, as could the Becker BK7 and BK9.
Is it a user or a looker you want?
