Outfitting an exotic weapons dealer in Faerun

Hey y'all.

Just looking to stock up an exotic weapons dealer as part of an adventure I'm preparing. Of course there I can give him weapons that are analogous to our word (a katana from Maztica, a khopesh from Mulhorand, a macuahuitl from Maztica etc.), but if people have any other realms specific things they can think of let me know!

Very minor magic items are fine, but obviously nothing that's super rare that would be out of reach for a high class merchant.
