Super chunky utilitarian Luzon bolo?

[wildwolberine]

Wanted to share this new acquisition. Large, heavy blade with a very thick spine about .75 cm at base. Substantial carabao hilt with a bump towards the pommel. Tang extends through the hilt & is peined over a steel plate. Thick steel ferrule. Simple wood scabbard with a belt hook. (You can barely see the projection in the last photo)

I suspect southern Luzon origin? The wood scabbard and large handle seem unusual. Probably the heaviest piece in my collection right now.

These are before-cleaning pics. Will clean the blade with WD-40 and 0000 steel wool and treat the horn with Hooflex.

Age probably midcentury? Thanks!

Dimensions: 56 cm overall length, 38 cm by 5 cm blade.
