How relative may the antique attribution be ?
Calling an end XIX century ear dagger an antique is eventually a figure of speech. Whether not well established if Nasrids brought this dagger from North Africa to the Iberian Peninsula as being a weapon of their creation or if indeed it has a previous (Oriental) provenance, the fact is that it is one of the more important contributions of the Nasrid panoply, like the jineta, was well available in their workshops in the XIII century; in such way that the only original example of this type, eventually belonging in the attire of Muhammad XII (Boabdil) when he was captured in the battle of Lucena (1483) is already considered by specialists as a 'later' version; in any case, an example matching with the adornments of a king, now in the Real Armeria de Madrid, the shield of the Nasrid sultanate figuring in its scabbard.
But a adornment was also the one we can see depicted in a portrait of King Emperor Carlos V (circa 1519).
So calling XIX-XX century examples a replica wouldn't be such a crime
