I've got 30+ years of serious martial arts training and instructing including tactical firearms, knife, machete and tomahawk seminars that I've taught as well. I've been a professional bodyguard for 20 years and have been in executive protection including escorts to Chad, Uzbekistan, Afghanistan and Iraq. I've had to survive nearly unsurvivable situations and I'm willing to bet my life on a coldsteel product. I hope that seals the deal!! lol
