Nice photos there. I have always liked the look of the SFNO better. Just more utilitarian design to me. That said, probably nothing one can do that the other won't handle fine.
That TB you posted without the choil, and the flat but looks great as well.
I really need to score a similar TB. No choil and flat but for hammering. I don't think I will ever have to bust a skull with my knife (although the Ash1 CG or the FBMLE would work).
