An unusual Luzon sword.
 

Unusual to me since I don’t recall ever seeing one that had a similar blade profile.
Blade is close to 25 inches in length.

That's a very interesting blade. I'm guessing the assembly was pre-1900 Central Luzon, Spanish or First Republic era. The fuller feature is curious- probably a one-of customization requested by the owner who's encountered Moro blades with such (the fuller outline reminds me of those on kris). Is there a false edge? I'm still on the fence whether the blade is also pure Luzon or something modified from Visayas (Luzon blades for that era are assymetrical edge grind- which I call a "fake" chisel. Visayas blades are "true" chisel edge grind).

The false edge measures at ~10 inches.
According to The seller, Peter A., this was collected in the 19th century.

The down-turned quillion and fuller suggest a Chinese influence to me. Also, does anyone think the bade may have been reworked or shortened a bit. The fuller just seems to trail off into the tip.

Makes me wonder, it seems fuller is a very rare or rather unusual feature for Luzon blades, although Tagalog has an archaic native term for it which is sanay, according to Vocabulario de la Lengua Tagala.

The down turned quillion does look Chinese influenced.

From the pics, the fullers look to be beautifully executed.
