CAS HanWei Bowie

It looks like a real knife to me, which is all you need for a knife fight.

This bowie doesn't look very historical. If you really want to practice American big blade fighting, you'd need a sharpened top edge -which is one of the real strengths of bowie/big blade fighting styles.

That Sheffield Bowie on the Cas Hanwei site looks like a more fearsome weapon to me.

Seeing where you live, you can probably learn more practical knife skills locally using big bellied knives.

nice looking blade. . . . .

fullering makes the blade lighter and more responsive but blade steel would be a more important factor in overall brittleness. Many swords have been made over the centuries with single or multiple fullers so don't worry about that in a shorter bladed weapon like a Bowie knife. 440C would not be my first choice in a fighting knife because it can be more brittle than 440A for instance and neither of the 440 series most often encountered would be my choice if a carbon tool steel blade were offered in the same design. I agree with CWL about the sharpened swedge - most historical Bowie knives had that feature and their narrower blade designs made them superior fighting blades IMHO.
