I have quite the suspicion that this is quite photo shopped. Angles on the blade seem way to crisp, if you had great pep I could see it but there also seems to be no drops or areas with resin built up. Also, the ground looks to have proper lighting with a flash from a camera. If a flash is there that shadow especially around the handle would not be as prominent as it is, should be more washed out.
I again could be wrong. If I am, I would love to see some photos of you holding it. You do have a timer on your camera right?
