ADVHARPOONF17MS: Harpoon F17 Flipper, Mil-Spec
Andre De Villiers Knives

The Harpoon is a 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 Mil-Spec Harpoon has a 3.875" harpoon spear point blade made from N690 stainless steel with a brushed satin finish. The F17 version has added a fuller, traditional of ADV's knives, for the 2017 production version. The handle is made from black stonewashed titanium with a matching sculpted titanium pocket clip.

The titanium lock has an integral lockbar insert/overtravel 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. This may not be your typical looking knife, but get it in your hand and you'll definitely warm up to the design thanks to all the great features it has and the fact that the action is on par with even the best flipping designs in the industry.
