Dagger with wavy blade

[Robert]

Hello Blue Lander, I would like to wait for better photos of this to be posted, but for now my best guess would be either the Philippines or Mexico. The Philippine people were/are great ones for using whatever was at hand at the time when making weapons. Also because this blade has a definite raised medial ridge giving a more diamond cross section it would not surprise me one bit that this could turn out to be from Luzon
I have also seen daggers and knives from Mexico where the same practice that whatever was readily accessible at the time was used in their production. Again I have also seen this kris or serpentine style of blade on many daggers made in Mexico, but most (not all) did not have a raised medial ridge. Instead they had more of an oval cross section. Either way it is a very well made little dagger and a great addition to your collection. Congratulations.

Best,
Robert
