He's known as the hammerhead because the strongman uses his forehead to hammer nails through wood and his Herculean jaw and teeth as strong as steel to pull the nails back out.

He's also pulled off several other head-scratching feats with his teeth, including pulling buses and trucks long distances, lifting weights, and even lifting people sitting on chairs.
