http://www.answers.com/topic/master-lock-company?cat=biz-finMaster Lock developed a television commercial for the 1974 Superbowl game that became notable in the public eye for its effective message and its identification with Master Lock. The "shot lock" advertisement, "Tough Under Fire," showed a blast from a high-powered rifle aimed at a Master Lock padlock.
