Looking for examples of Philippine weapons from uncommon places
 

I am looking for documented examples (i.e., firmly identified) of edged weapons from several areas of the Philippines that we seldom mention: the South Tagalog region, southern Luzon, and nearby Visayan areas. Moving from west to east:

Palawan (northern half)
Mindoro
Tablas, Sibuyan, Marinduque
Masbate
Leyte
Samar
Bicol

The reason I ask is that I am having trouble placing a number of pieces that seem to have transitional or crossover features, between traditional styles of "Luzon bolos" and of Visayan swords and knives.

Batangas is one transition area that we have discussed several times before, and it certainly has swords and knives with shared features. But the pieces I am looking at do not strike me as coming from Batangas -- hence a search for more information about other possible transitional zones.
