Help, anyone familiar with such a knife?

[tbird914]

I have a knife that was my grandfather’s and was hoping somebody might be able to give me some information on it. I’ve only come across one example of a item with similar markings, but it was on some auction site that was very very old so all the information on that item was removed other than the amount it sold for and I’m sure that was false as the amount was a bit far fetched. The only information that I came across would be that it was South American, possibly and sort of boot knife.n Any and all help is much appreciated.

Thanks.
