In imagining the blade the Balangiga bolomen used, the following passage from Borrinaga's
The Balangiga Conflict Revisited would be relevant:
He [1st Lt. Bumpus, the second-in-command] noted the "great many coconut trees along the lowlands near the seacoast." He added that the "meat of the coconut and its milk are highly prized by the natives, and they get a good price for the oil." ...
It could be inferred from the above observation that, unlike western Samar towns around Catbalogan and Calbayog that engaged in hemp production [thus abaca instead of coconut would be the main crop], Balangiga in the south was more into coconut oil production for export. [p. 43]
Earlier, we saw that the Leyte-Samar coconut farmers' bolo of choice would be the
talibon (also known simply as
sundang among the natives).
So that must be it ... the Balangiga encounter would be a talibon vs. Krag encounter, if we may wrap up the type of weapons used in the Balangiga incident.
