Second Chance is a body armor manufacturing company and was the first one to use kevlar for body armor. The company was founded in the early 1970s by former U.S. Marine and pizza delivery owner/driver Richard Davis. Davis developed the idea of a bulletproof vest after shooting three armed robbers in self-defense during a delivery. This incident was later documented in a 1995 book written by firearms instructor Massad Ayoob called ''The Ayoob Files: The Book''. According to Reader's Digest April 2014 "Extraordinary inventions by ordinary people", Davis did not do the shooting but was the victim, being shot twice. Davis started his company out of his garage. In early sales demonstrations, he would put on one of his vests and then shoot himself, usually with a firearm provided by whatever agency he was demonstrating for. In 1998, Second Chance introduced Zylon-based body armor (bullet-resistant vests), as a lightweight alternative to kevlar. The Zylon material used in the vests was supplied by Japan-based Toyobo. In June 2005, the National Institute of Justice, the United States government agency responsible for developing safety standards, determined that these Zylon-based vests did not meet the required standards and may be defective. The United States Department of Justice advised law enforcement agencies to replace the vests used by police officers. On August 2, 2005, Second Chance was acquired by Armor Holdings, Inc. for US$45 million. == Further reading == * Ayoob, Massad (1995). ''The Ayoob Files: The Book''. Concord, NH: Police Bookshelf.
