A U.K. carpenter accidentally chopped off his own penis while sawing timber to build a cabinet, his mother says.

Stuart Keen's mother, Edna, said her 54-year-old son was cutting wood when he suffered the horrific accident.

Keen's mother said surgeons were able to reattach the severed appendage.

"Stuart is a carpenter and uses sharp and sometimes dangerous tools," his mother said. "This was an unfortunate accident, but these things happen all the time to people in his profession."
