Very nice arrowhead! Very nice HK and WD for that matter!

My father and I found quite a bit of Native artifacts in 1988 when we were regrading his yard outside Redstone Arsenal (Huntsville Alabama). He knew someone who dated them about the same period as yours. There are a couple larger pieces including some stone implements 5" x 3".

I have everything stored in my attic. I've meant to build a shadow box, but never did it. Maybe I'll make that project a priority.
