I grew up in a small town in the Ozarks, some boys whittled, but I don't recall anyone that young with knives, especially around other young children. Boys I knew that whittled didn't start until 11/12, nowhere near that young. If it is a knife in his picture, that's very alarming to me that he was allowed to have a knife at that age, especially around other children, and his brother whom he tried to drown when he was 4. I can't see if it's a knife or not because I don't have facebook and it puts a large banner over the bottom part of the picture, which is why I really wish people could post the picture they are referring to.
