I'm not sure that "Base Tang" is the right classification for this artifact. It has small notches on the base so that's what I'm calling it. Any comments about what it may be are appreciated. I'm all ears. I can take more pictures if needed.
Well, I find your assessment quite reasonable. It appears to have an unusual symetry in the area of the edge damage. I am left with a sense of intrigue about what it looked like before the damage! Was this a surface find? Thank You for sharing it with us.
