The best of the best! These OTF (Out The Front) Automatics have blades that eject by spring force through an opening hole in the front of the handle. The majority of the knives shown in this section are single action: They shoot under spring power with the press of the button and reload via a charging lever that hides in the handle when not in use. Double Action (D/A) OTF Knives have dual action spring systems and the handle button is used to deploy and retract the blade. Only two knives in this section are not spring powered they are the Colt Czar and the Phantom Rip Cord. The latter are considered gravity knives.
