The folding hunter pattern is pretty common, most of the major knife companies made one or more variations of the pattern.
Just like naming the pattern, naming the blades is up to the company that makes them. Camillus called the secondary blade a Turkish clip blade, Schrade called the secondary blade a skinning blade. Ironically they were owned by the same man.
Both the Folding Hunter pattern and the "Turkish clip" or "skinning blade" are the standard secondary blades on the standard folding hunter patterns.
There are variations that do feature a saw blade instead of the skinning or Turkish clip blades, cool variations but not nearly as common as the standard folding hunter.
Hope this helps.
