Looks simular to a small leaf blade or could be a preform. Its not always easy to ID blades unless its a specailty blade. For instant, if you was to find a lot of the same from a certain culture you can be fairly accurate that the blade is from that culture eg Hopewell. But regular blades were disposed of, so they just knocked them up ( pardon the pun) lots of them, & just basically tossed them away.
Looks archaic though. Nice lil blade/preform.
I'm sure the MO collectors will ID the points.. Nice finds.
