There is a very interesting article in today's Wall Street Journal about the business side of tactical knives ("How New, Deadly Pocketknives Became a $1 Billion Business"). It discusses tactical knives, including keyring knives, from the business side of things. People like Jim Ray, Mike Janes, Dave Vanderhoff, David Kowalski, Ernest R. Emerson, and others, and companies like Spyderco, Cold Steel, Benchmade Knife, Buck Knife, and others, in the context of the popularity of tactical knives and efforts to avoid having a knife being labeled a switchblade. One-handed opening and the legal problems it brings is a big topic; Leatherman Tool Group's "Blade Launcher" is mentioned, for example. The FMAs get an explicit mention ("Modern tactical knives are rooted in the 1980s, when some martial artists became practitioners of a Filipino style of knife-fighting"--hey, that could be Modern Arnis!). It discusses blade length and the 9/11 hijackings. Disturbingly, at the end of the article it mentions that some companies are pushingh plastic and ceramic blades, including assisted-opening knives that are described as capable of being taped anywhere on the body. Some items from this very worthwhile article (which should be available for purchase at www.wsj.com in one week): -The FBI says that knife-related crime is up (15.5%in 2004 vs. 15% in 2000), while violent crime overall is down -In March, the FBI's monthly bulletin for LEOs warned of the dangers of the newer knives, with their tactical designs and ease of concealment; -One shop owner in Calif. states that 75% of the pocketknives he sells are tactical; -Industry lawyers have worked to keep any blade that requires manual assistance to be opened from being labeled a switchblade; -Emerson has sales of $10 million per year; -There is disagreement over how to market the knives--whether or not to tout their deadliness; -"Technology has made blade length almost irrelevant" (the newer designs are deadlier--serrated; ergonomic, etc.), and in Atlanta, for example, the blade length limit is 2 inches; -More knife sellers are adding training in tactical use of these knives. If you can find this article, I think you'll find it interesting reading!
