I am certain that I have seen a similar knife categorised as 'Moroccan', a hop. skip and a jump from Spain. (Possibly a trade knife?) Conversely, many areas of Southern Spain are steeped in Moorish history, could these knives have been manufactured for their Arab brethren ?
Certainly the Med. has been a hot-bed for trading for thousands of years, so the idea of cultures copying designs of knives goes without saying.
Is there a scabbard?
