The Fly Father is a departure from traditional Protech knives, but it retains the classic blade shape of the Godfather/Godson knife and incredible fit and finish. The blade on this knife is 154-CM steel with a black DLC finish. The front side of the blade has the Protech logo and the back side is marked "First Run #** of 30".

The handle is comprised of titanium slabs with beveled edges and grooves along the sides. The titanium frame has zen pins and barrel spacer construction while the pivot features 56 ball bearings (14 per pivot side) and set-screw pivots that allow the user to adjust the tension on the blade for smooth and precise action. The latch is quite unique and a work of art itself! It is an arc shape, which allows the blade to extend closer to the handles bottom edge when closed. It's a nice touch that makes it possible to have a longer blade than is otherwise possible. The latch also features an integral latch stop which keeps the latch from hitting the blade.

The FlyFather follows the tradition of other Protech Knives with its attention to detail and exceptional fit and finish. The FlyFather is a great addition to not only Protech's line, but the Balisong community too.

This FlyFather has black DLC finished handles and blue anodized titanium pocket clip and latch.

Pretty D NICE
Kevin B.
At first the bearings may be a bit tight, put some light oil recommended by Protech. After that you will be more than happy! I admit, the handles could be lighter, never hurts to add some holes to work with weight and balance. Please consider that in future productions.

Overall, without a doubt in my mind, high quality and worth every penny! Just work with it and break it in properly.

It really is a wonderful work of art!

Thank you Pro Tech!
