Geometrical Fruits

Have you found a fruit with sides on it? As long as I know, naturally there is no any fruit with sides. But, anything is possible to be done. So, I accidentally found an interesting art by Sakir Gokcebag on his website http://www.sakirgokcebag.com. The interesting thing here is not only about the geometry shapes, it is also original with no digital manipulations but with the knife skills.
