The Paragon PARA-X OTF knife is the next generation of the ATKO-10. This Asheville Steel automatic is a single-action, out-the-front knife. Just push the button and the blade fires out the front of the handle. To close the blade, just press the button and use the retracting lever to pull the blade back in. The PARA-X has a sliding safety under the firing button and a pocket clip for easy tip-down carry. Made in the USA!
