We found the piece of a pre-columbian knife done in obsidian a very common material used by all the different tribes in America. You can tell it was a knife by the double parallel chisel on the sides (pic 1) a cut that make a thin cutting edge (pic 2). On the top, you can see the flat place where they hit the stone to separate it from the bigger piece (pic 3) and on the back the ripple effect left on the stone from the impact (pic 4).

I'm happy to have stumbled across your blog. I'm going to read past posts, but I'd like to know if you would be willing to e-mail with me. I am an author who has set a book in Guatemala and I would love to get some feedback from you on if I am accurately portraying things.
