Paragon Estiletto
The Paragon Estilleto is based on the ATKO single action out-the-front design but it has been super-sized. Push the button and the knife fires out the front of the handle. To retract the blade just press the button in and use the retracting lever to pull the blade back in. The Estilleto has a pocket clip for easy tip-down carry and a safety to ensure the knife is not fired by mistake.
