AM3 blank question
So I'm filing down my AM3 key blank to start an impression just to make the top smooth and I notice something I notice every time I smooth out my keys, two distinct marks that look like pin marks, but they are not. I just ordered calipers so when they arrive I'll measure to see if they happen to line up where the pins would, but these have a habbit of throwing me off and I can't keep smoothing out or the key will not be cut right, well it could be but still.

The key has not been put in the lock these marks appeared as i filed it down a little to get a smooth look. Anyone else come accros this?
