Jim Wagner, from California, has had many bad experiences with attacks on himself as a police officer, a law enforcement officer, a SWAT member, a soldier and a bodyguard. This has resulted in his "Reality Based Personal Protection" system. Many international Special Forces use his techniques and have been trained by him, among others in Germany, Israel, Brazil, Mexico and the USA. His designs are absolutely useable in operations, his longstanding experience flows into every single knife.
