Corner Notch ID needed. Small but robust

[Arrow1632]

This was from far NE Illinois. Impact fracture likely. Small but likely reworked.
I have an idea on type but like to hear what the experts say as I am somewhat new to arrowheads. On one pic I added the corner in photoshop to show how it would have looked. Thanks

Not enough left for me to say maybe someone else will know

It’s a little odd they’d re work the tip but leave it that shape… if you don’t care about the pointy bit then I’d guess a knife. I don’t know types in your area but maybe look into side notched types
