I think these little ones are indeed corn razors. As sold by retailers, such as Wells on Strand, I wonder if it was not part of a grooming set. The little fella would be exactly like it's big brother in the set.
In any rate, I don't think much of smaller razors being called 'travel' razors.
Could not save much weight and space over a regular-sized one?
A nice little razor, that one!
