flaming blade old dagger
 

I need some help, please.
This is one of two old pieces i bought yesterday in a little country "antiques" shop.
I am not sure if "flaming blade dagger" is its correct name in english, which then would be the strict translation of portuguese "adaga de lamina flamejante".
It has a very strong blade, 9 1/2" long, and is over 5/16" thick, slightly reducing to the tip. The wood handle is slim and of less strong concept, with some basic turnings. Also very fragilised, as mostly worm eaten in the inside. It has a 1/2"brass ferrule, almost completely dirty and oxided.
Could someone help to classify this dagger, in terms of tipology, possible age, and major use context ... military or personal defence/ofence.
Or eventually any other remarks that may occur.
Thanks a lot.

Not my area, but I suspect this is a Moro spear head that someone has
stuck a handle on to convert it to a knife. I'm sure others will voice
their opinions; hopefully more knowledgeable than I.

I agree with Rich, it looks like one of the Moro waved spearheads, although the bottom of the blade ends in a non-traditional fashion.

Thank you both gentlemen for the important info. This explains why the handle was so unbalanced for such a heavy blade.
Any guess on its age ? Can i advance 19th. century ? I mean both blade and handle mounting, as the condition of the ferrule and the wood ( i've pictured the best part ) shows it's not a contemporary job.
Is it possible that this type of spear was used in Timor ? I wonder how this piece showed up so distantly as Portugal ... Timor was our last connection over there.
Thank you for further help.

I also agree,very cool Moro spear head. Congratulations! :)
