Along with its top-of-the-line quality materials and design, this Redencion 229 features the Lee Williams Kickstop flipper tab. Unlike most flipper knives, the Kickstop flipper tab isn't a part of the blade's tang. Instead, the tab is attached to the frame by a separate pin. This means when you open the blade, the flipper tab rotates on its pin and conceals itself within the knife's handle. Not only does this keep the knife looking sleek, but it allows you greater flexibility in handling the knife as you put it to work.
