Can anyone identify this blade?

[Chad Scott]

I was looking through my late grandfather's office recently and came across his souvenir blades. He and some of my uncles traveled quite a bit in the past, and when they did they would bring back some of these souvenir blades for others in the family. I came across several kukri, a pair of rough daggers from Africa, and this larger copper blade. I dont recognize it, and it very well may be just one of those pieces made to sell to tourists without any real style or history.

Either way I thought it was cool, and wondered if any of you with more experience would at least know a general area that it could have been made in. All of his things had a story, and I am dissapointed I dont know the story behind this one
