From the Blackbird Knives Designer: Paul Sheiter "I believe the more complicated a product becomes, the more likely it is to fail when your life depends on it. For this reason I designed The Blackbird SK-5 Knife to achieve maximum function delivered through pure simplicity. You won't see gimmicks or gadgets on this knife...only the core essentials that provide the user with comfort and a sharp edge to handle the most demanding wilderness survival tasks." -Paul Sheiter
