Talismanic inscriptions on a Barong

[VVV]

I hope some of the Moro experts can help with explaining the signs on this Barong?
As I understand it's a double edged Shandigan?
- The Ring of Solomon I recognise but what's the "cross tongue" below it?
- Is it a dog or something else depicted closest to the tip?
- Is it a naga or a centipede at the other side of the blade?
- And what's the meaning of the symbols?

All comments appreciated.
