From several Cuchillos de Albacete that i have seen, besides being hard to find them with sheaths, the ones we spot follow a different pattern; basically made of leather and sometimes with a couple brass trimmings.
But i am miles away from being an expert on these things. My hint was more intended to take you to go deeper into the matter yourself; like, for instance, checking how tight the blade fits into this sheath .
I don't know why but, this scabbard looks to me like having a Gaucho touch.
Others will surely be able to tell whether i am talking nonsense
