Finding an Indonesian keris with two different pamors on each side of the blade is relatively rare, but this is the first time I have seen the effect on a Moro blade. Note here that one side shows a more common linear pattern connecting in a flame-like point at the end of the blade. The other side is more of what we would expect to see on a twistcore blade or "chevron" pattern weld.

The white edges are also new to me so I consulted our resident metallurgist and forging guru, Philip Tom, to learn that these white edges were a hard iron core partially exposed by sharpening for an edge.

The two pattern blade is more common in China, Japan, and Korea, and Phil theorized that the skill likely came to SE Asia via trade and skilled craftsmen from those areas.

Interesting blade!... Perhaps a forger showing off his skills!
