Sog Flashback

Well-balanced and razor-sharp right out of the box, the pocket-size Sog Flashback is a knife worthy of any adventurer's kit. What's more, Sog claims the 3.5-inch stainless steel blade is the fastest assisted-opening knife on the market. Hyperbole, perhaps, but it's certainly the quickest we've ever tried. [$100; sogknives.com]
