Thanks Dave! This is the first time I've seen these patterns side by side. That sorts it out.
The confusing part really comes with similar patterns made by various makers -- often what they call a city knife and what they call a stiffhorn seems to be pretty arbitrary. I've seen similar patterns with anything from a 2" blade to a 4" blade called a "stiffhorn" (and similarly with "city knife").
Actually this may not be the makers fault - since I've been seeing all of this terminology abuse on various custom dealers sites.
