Pinahig Ifugao Bolo?
 

This looks like a cross between a Pinahig Bolo & a Panabas, maybe a Pinahigasaurus? It looks much larger than the traditional blade, even though it conforms to the general form. The blade measures approx. 13" long,4.25" at its widest,7/16" wide at the base of the spine, and 22" in total length. It is very heavy and it has a beveled edge on each side.

Hi drac,

That's a recognized blade pattern in Northern Luzon mountain areas. It is a tool more than a weapon, I believe. Perhaps one of our Filipino experts can give you a specific name.

A beast indeed. I have this beefy pinahig at 20.5", however it has a more typical pinahig profile.

I know there are only so many ways a weapon or tool can be made,but it fascinates me how Naga use the same construction method, albeit with timber/Bamboo cores in their handles and the weapons from Taiwanese Aboriginals also use this construction method.

How prevalent was trade between Taiwan and the northern Philippines?
Is it thought that this style of manufacture was introduced from Taiwan?

Here's another one of similar size.

Trade between Taiwan and northern Luzon goes back centuries. Genetic studies have shown historical interbreeding between native Taiwanese and Filipino groups among residents in Taiwan and the northern Philippines. Where the socket hilt arose is unclear, biut cross-diffusion seems likely.

It's a pehlet, it's a type of pinahig as far as I know.

Thanks to all for the insightful information, especially its proper name, "pehlet."I too have often wondered about the similarities between the construction of weapons of Taiwan and some areas of the Philippines.
Also as already mentioned by others on the thread, certain features of the Naga blades, including the open-faced scabbards.
