Benchmade Infidel Automatic Out-The-Front Knife - The Infidel's out-the-front mechanism is smooth and rock solid. The Infidel features a double action out-the-front action. That means that the blade is both deployed and retracted by spring pressure generated by user pressure on the slide release button. Using a double edge spear-point blade, the Infidel creates a style all its own. Feature D2 tool steel for the blade, and black anodized, machined 6061 T-6 aluminum for the handle. This knife has a removable deep pocket carry clip and a ballistic nylon sheath for multiple carry options.
