ADV Tactical Harpoon F17 Smooth FDE


Out of stock


The Harpoon is a heavy duty tactical flipper from Andre De Villiers that might be his most refined design thus far. It has elements of the Butcher design that came before it but the addition of the second finger groove and thumb ramp in the blade make for the stellar ergonomics, much like the Hummer model. It’s smooth, fast, sharp and stout – really everything one could want in a tactical blade, and can easily flex into EDC, hunting or survival tasks. The Harpoon has a 3.875″ harpoon spear point blade made from excellent N690 stainless steel with a satin finish. The F17 version has added a fuller.. The handle and pocket clip are made from milled titanium with a bronze and black anodized finish.

The titanium lock has an integral lockbar insert/over-travel mechanism that provides solid lockup while being very easy to disengage. The pivot point, though, is what sets this knife, and all ADV blades, apart from the others. It has an inset Torx screw that fits inside the pivot, allowing you to tighten down the pivot while adjusting the centering or overall smoothness of the action. The action is very smooth to say the least. Jimping on the redesigned flipper tang and thumb ramp are sharp and functional, nothing was overlooked for this awesome design. The right-hand reversible milled titanium pocket clip of the Harpoon has been redesigned to allow for better retention in thick pant pockets and incorporates a rolling ball design for an easier draw.
