Inquiry about kalis engraving
 

Greetings, was just wondering if anyone else has encountered a particular engraving on a kalis blade. I'm currently restoring this kalis and resetting it to a new hilt (which looks similar to the original one, except the latter had nylon wrap). Please post an image if you have a similar engraving on your Bangsamoro weapon/s. The engraving looks as if there's a person at the threshold of an open passage. Other interpretations are welcome. The piece only has a roughly made scabbard, obviously not its original. And don't worry about the epoxy, I'll clean it up later on.

TIA!
