The A-OK utilizes Blackie Collin's patented mechanism for an assisted opening folding knife. All previous mechanisms for this type knife rely on torsion or coil spring which is positioned beside the blade. The A-OK uses a simple leaf spring which is directly in line with the blade and allows all knives using this mechanism to be much thinner than those using the old system. The choice of handle materials is enhanced and a knife need be no thicker than its blade and a layer of any handle material strong enough to make a good pocketknife. Durable, ultra fast opening with the slightest pressure against the easy to use thumb stud. Lockback includes pocket clip.
