Yes, i would agree that these double blawongs are being made commercially with the intent for display. However you stated earlier:
If we display our keris in a even quantity we are, in my opinion, exhibiting a lack of cultural sensitivity, and acting in a way that could draw anything from a quietly amused smile to harsh criticism, from people who are Javanese, or who are accustomed to Javanese mores.
For me this begs the question, why then would Javanese people who are accustom to Javanese mores create such a display piece for the commercial market? It seems unlikely that they were being swamped with requests from foreigners who don't know any better for double blawongs. So would you say then that possibly the idea for these is born out of a more ritual concept of being intended as a protective display for the home, meant for an esoteric pairing of two keris? Otherwise i don't understand why Javanese people would get the idea to commercial produce these in the first place.
