Carbon fiber doesn’t hold much of an edge, but anyone who owns an ‘Executive Letter Opener’ knows that even Zytel can support a wickedly strong piercing point. These daggers from carbonfibergear.com may not be technically legal aboard airline flights, but their nonmetallic construction could certainly help you obey the 11th Commandment and simply not get caught.
These knives are between 7 and 9 inches in total length, and each weighs less than one ounce. The blades are built up from 12 layers of unidirectional carbon fiber, with an outer layer of twill-weave carbon fiber composite. The handles are 32 layers thick, presumably to provide a better grip.
While I could see these knives as cool James Bond gadgets or very clever letter openers, they have no advantage over conventional knives other than their ability to sneak through metal detectors. They would still be discovered with a body surface scanner, and a diligent pat-down (as differentiated from a TSA frisk) would find them in a heartbeat.
