Steven Seagal is a Martial Artist who should need no introduction. He found international acclaim and celebrity for his high-octane Action movies, but he is first and foremost love is the world of Martial Arts. With an encyclopedic knowledge of the Japanese warrior arts, a 7th Dan Black Belt in the art of Aikido and a lifetime of training, he is still a much-in-demand instructor and consultant. Whether working specialist techniques with UFC stars Lyoto Machida and Anderson Silva or travelling the world teaching seminars, there is no doubt that Steven is still a force to be reckoned with. The "Helmet Breaker" of old was an incredibly powerful off-hand parrying tool and percussive weapon used by Japanese Warriors. It was used to block, hook and parry an opponent's sword at longer ranges and to manipulate, wrench, and bludgeon at an opponent's armored head in standing / grappling range. Rumored to be capable of prying open armor like an oversized battlefield can opener, there's no doubt it is more than capable of denting helmets, crushing skulls or breaking bones with sickening ease.
