Looks like it could be a tilling blade. I usually just classify finds like this one as "B.A.I." or, big azzz iron, chalk it up as a learning experience and move on.
As Skaba says ...... if it has two holes
, more than likely it is off a Chisel Plow .... chisel plow points have a slight twist to them so they roll dirt right or left depending on how the points are mounted on the tines ....
