I think David is correct in reading the tag Daho.

I found two more in my brace of Southeast Asian spears that have a reinforcing tie of the head to the pole, one is again wire but the other is twine. Most of these lances have come from gun shows, so likely they are war souvenirs from the turn of the 20th century and, now that I am looking, at least a third in the collection have these reinforcements.

I'll agree in speculating that sometimes the heads were getting detached and that this would have been a "field modification" to prevent such failure. Next below are a couple of spearheads where the tang is visible and may be seen to not be especially long.

I have never been able to work out the chronology or geography of the various blade styles. I very strongly suspect that many are significantly older than is generally accepted and documented. Look at the dark brown patina on the exposed tangs: one uncovered over a hundred years ago while the blade remained bright and the other protected by resin until I dissolved it off. Then consider the patinated appearances of the tangs of Japanese swords which may be dated from signatures.
