"In 1986-87, I conceived the ATCF drawing inspiration from my experience with military and security personnel both in Central America and in the United States. My goal was to create a unique knife: lightweight yet robust, easily accessible and comfortably carried on various articles of clothing, completely corrosion resistant, with ambidextrous functionality for opening and closing, and usable with one hand. The ATCF marked a turning point in the tactical knife industry, being the first to be entirely assembled with screws instead of pins and rivets. I introduced the thumb disk to facilitate opening with both hands, an innovation widely imitated by knife makers worldwide. Among the distinctive features of the ATCF is the serration on the top of the blade that matches the finger guard at the base of the handle when the knife is closed, providing protection and a secure grip during use. Additionally, the ATCF was the first pocket knife to utilize a pocket clip, allowing versatile accessibility in various body positions. The ATCF deeply influenced the world of knives, becoming one of the most imitated models. As I like to say, 'The ATCF is the classic form that has shaped an entire industry!'"
