David,
The differentiator between a `cuchillo” and a `cuchilla’ (feminine gender) is primarily by the extent of the blade’s belly, the more pronounced ones belong to the last mentioned class. Often the differentiation is not easy to make because `cuchillos’ also have a belly and a significant overlap exists.
`Cuchillo/cuchilla de campo’ generally refer to sturdy utilitarian knives of substantial size and does not refer to a specific traditional sub-type of regional knives. Domenech acknowledges in this thread, post #27, that he arbitrarily made up this class of knives in his book Dagas De Plata:

Domenech’s rather late and narrow definition is not necessarily shared by others, as exemplified by this knife from the renowned Argentinean blade smith Gugliotta:

And all of these are considered also `cuchillos de campo’:

So if we use Domench’s definition then it cannot be a `cuchillo de campo’ and it must be either a mere `cuchillo’ (knife!) or a `cuchilla’ (a knife with a pronounced belly). However, I still class it as a `cuchillo de campo’ or perhaps a `cuchilla de campo’
Since the genre made its appearance rather late, I would not be surprised if it is not simply a local rendition of what we would call a `camp knife' and hence the name.
Cheers
