Additionally, sir Ian: as I have gleaned from the elderly pandays in Ilocos, I have updated migueldiaz / sir Lorenz regarding the classification of Ilocos blades. The labeling of sinan- is only part of the classification. The complete classification runs thus:  
 
Name of hilt (sinan-kapitan, sinan-Gabriela, sinan-bukelbukel, etc) + blade profile .  
 
For example, in this modern blade I got from Santa, Ilocos Sur, the formal classification would be "sinan-kapitan na bulong pagay." Bulong pagay is the blade profile.
