The Estilleto is based on the ATKO design, but it's been super-sized. Just 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 retracing lever to pull the blade back in. This out-the-front knife features a sturdy coyote tan coated T6 aluminum handle. The CPM-S30V DLC finished blade features the highly requested double edged dagger blade with plain edges. The Estilleto has a pocket clip for easy carry (tip down) and a safety to ensure the knife is not fired by mistake. Made in the USA and new in box.
