It was pointed out that the top one does not have a guard. I presume that would mean that the top knife is more likely to be ceremonial than as a knife used for fighting or dueling. Especially as it was purpose made. A decent "purpose made" fighting dagger would have a guard I presume (like the Bowie). Surely if "you" didn't have a guard but were going up against someone with a similar knife but with a guard then this would place "you" at a disadvantage.
