What is this?

I found this a few months ago and thought it looked a lot like a hatchet blade or something. Is that close or is it a handheld scraper or something else? Found between Zapata and Laredo, TX about 10 mi N of Rio Grande River. I meant to photo with something for scale but forgot. It's around 4.5" long and 3.5" wide at the front cutting edge.
Thanks, Blair S.

Looks like a scraper to ME...

I was thinking the same thing. It would make a wicked tomahawk though.
