Jack "Hacksaw" Reynolds is a former American football player who played for the University of Tennessee, and started out as a fullback and changed to linebacker. He was a first-round draft pick by the Los Angeles Rams in the 1970 NFL Draft and played there 11 years before going to the San Francisco 49ers in 1981. He played with the Niners four more years and won two Super Bowls with them: Super Bowl XVI and Super Bowl XIX. He wore the number 64 throughout his career. He played in a total of 13 postseason games. Reynolds currently splits his time between a house in Miami and another in the Caribbean.
Reynolds earned his nickname in 1969 by cutting an abandoned 1953 Chevrolet Bel Air (some accounts claim it was a Porsche) in half with a hacksaw after his previously unbeaten University of Tennessee team returned from an embarrassing 38-0 road loss to Ole Miss. "I came back to school and I was very upset," Reynolds said. "I had to do something to relieve my frustration." He decided to turn the abandoned car into a trailer for his newly purchased Jeep. After working through the night on the project, chewing through 13 hacksaw blades, he returned the next day with some teammates to show off his handiwork. However, when they arrived, both halves of the car were gone. For the remainder of his career, the nickname stuck.
