Actually, that's a pretty common blade, Spunger. It has has all the trademarks of an Ilonggo bolo: typical scabbard with leather throatpiece and brass bands, knob hilt pommel, long iron or brass ferrule, chiselled-edge. Even the blade form is common. Sure, you could call it a talibong, but a talibong denotes a blade specifically made for fighting. The blades are usually longer and more slender and a handguard would most likely be present as well. Your example is more of a general purpose bolo that can be used for anything from fighting, cutting up brush, to chopping up the lechon for dinner
! If you want to get more nomenclature specific with that particular bolo of yours it would also depend on what region of Panay or Negros that bolo is from. The Ilonggo term would most commonly be called just a sundang or itak or even binangon...although we normally think of a binangon as the type with the straight-edge and a spine that curves down to the edge like a sheepsfoot blade on a pocket knife. And even then are we talking Ilonggo terms from Iloilo or Negros. To add more confusion...the fighting version of a binangon is a ginungting. In Aklan, your bolo would be called a sanduko which is your general purpose work bolo. In Capiz, the Sanduko refers to the older form of diety-hilt tenegre that we know. Are you confused now? Anyways, here is a picture of three Ilonggo blades. The top one is a talibong from Mandurrio, Iloilo circa 1942. It has all the Ilonggo trademarks as mentioned before and the more slender fighting blade and crossguard. The sundang/sanduko is in the center and is similar to your example but slightly older. The bottom sword is a recently made binangon I grabbed out of my mother's gardening bucket. The blade and hilt is typical as well as the scabbard, but it has rattan wrap instead of brass/aluminum bands and a pigskin throat-wrap with the hair still intact. When Shelley and I were in Hinigaran, Negros, he bought a couple newly made binangons/sundang at a market that were a little cruder than these, but suprisingly very similar. I think he paid a couple hundred pesos for each one...about $3. Nothing fancy, but quite functional. Maybe he'll post pics of these sometime. Finally, the last picture is a really old old bolo of the "plamenko" form. Morningstar is selling newly made ones that are very similar...this is an original that I wanted to post for comparison and to show that there are other blade forms in the Visayas besides your sanduko or binangon form. Hope this helps and doesn't confuse you more.
