Peter Lagana – Creator of the Vietnam Tomahawk Carl Cestari & Clint Sporman 1997
Clint Sporman began his training in Combatives in 1992, under Carl Cestari. Cestari was internationally recognized as one of the World’s foremost authorities on authentic WWII Close-Quarters Combat. Cestari’s system was based greatly on the methods taught by William E. Fairbairn & Eric A. Sykes, as well as his own personal experience. Sporman continued intensive systematic training in all aspects of Close-Quarters Combat for the next fourteen years until Cestari's untimely passing in 2007.  Mr. Cestari designated Clint Sporman, prior to his passing, his number one protégé, and his official successor upon his passing. This designation is unanimously recognized and supported by Carol Cestari, Cestari’s longtime cadre of instructors and closest friends.
