The only sources I have for visayan longswords and other weapons are:
- William Henrys scotts:
Barangay
-
The Philippine Islands, 1493-1898 - Volume 40 of 55
1690-1691 Explorations by Early Navigators by Antonio Pigafetta
Although Williams book talks into more detail about weapons and even armor, there isn't isn't too much detail on the swords they smithed themselves or how succesful they were against their moro counterparts.
