I thought you said it was at the heel but I see what Bluesman is talking about. Maybe it's lighting but it looks like there's one near the toe also.
Looking at that pic again that is some pretty wicked magnification. Based on how high the magnification looks it should probably hone out fairly easily. But first FIX THAT UGLY ASS HEEL. And I mean that in the nicest way possible. It's easy to be shy of taking that much off of the blade because you can't put it back on but that is nowhere near trimmed enough.
Make it look something like this:

See how much more appealing that looks? AND the stabilizer is out of the way.
