The SWBLOP4 offers all the speed and convenience of an automatic knife in a well designed spring assisted package. If you're looking for a sub $50 spring assist knife chances are you won't find anything better than Smith & Wesson's Black Ops SWBLOP knives.
The Black Ops 4 series utilizes Smith & Wesson's M.A.G.I.C. assisted opening mechanism. Just a small nudge of the flipper or thumbstud opens the knife. The action on this knife is great and it locks up tight via the liner lock frame. To prevent unintended firing, there is a safety on the handle. The aluminum scales are grooved and comfortable in hand. The Black Ops 4 blade is black coated 4034 stainless steel with thumb notches on the thumb ramp. Comes with a pocket clip and lanyard hole.
