The Fly Father is a departure from traditional Protech knives, but it retains the classic blade shape of the Godfather/Godson knife and their 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.

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 bottom edge of the handle 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, a very unique feature! Includes matching anodized pocket clip.

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

This FlyFather has solid blue orange-peel anodized handles and a pocket clip.

Nice Butterfly
michael b.
Protech quality has always been top notch, and the Fly Father is no different. The fit and finish are excellent, and the ball bearing pivots are really smooth. I like the fact that the pivot pins are adjustable, and do not require the use of locktite. The blade is well made, pointy as hell, and very sharp out of the box. The titanium handles are actually pretty comfortable even though they are a bit square. For my personal tastes, the weight of the knife is decent, I can flip it and maneuver it easily. Here are my gripes... The lock is a pretty a cool design, allowing maximum blade length. I do find it a little sticky at times, you have to center the handles evenly, and give the handles a good squeeze to set the lock. Although the materials are high quality, and the build is close to perfection, I don't believe this is a $500 knife. I own knives that cost two to three times as much, as well as much less. I don't think this is a "you get what you pay for" knife, hence my four star rating. Other than my minor complaints, this is a fine blade.
