The R.A.D. Keychain Defense Options course is one of the only realistic and court-defensible impact weapons programs available for the general public. Combining proven R.A.D. Physical Defense strategies with revolutionary impact weapons defense techniques makes this program a worthy addition to the R.A.D. System. Realistic employment, combat effectiveness, "light impact", fluid transitions and even simulation training exercises are all part of this program. This program revolves around use of the Kubotan in conjunction with weapon-enhanced physical skills. This is an additional 4 hour class for "RAD Grads".
