At some point, the Club was mentioned. The professional thieves laughed and exchanged knowing glances. What we knew was that the Club is a hardened steel device that attaches to the steering wheel and the brake pedal to prevent steering and/or braking. What we found out was that a pro thief would carry a short piece of a hacksaw blade to cut through the plastic steering wheel in a couple seconds. They were then able to release The Club and use it to apply a huge amount of torque to the steering wheel and break the lock on the steering column (which most cars were already equipped with). The pro thieves actually sought out cars with The Club on them because they didn’t want to carry a long pry bar that was too hard to conceal.
