    • Fly Father 2

    Pro-Tech FlyFather 2 Balisong

    The Pro-Tech FlyFather 2 is a collaboration between Pro-Tech Knives and Squid Industries — two American manufacturers who brought their respective expertise to a single platform. Pro-Tech contributes the machining precision and blade quality that comes out of Placentia, California, while Squid Industries contributes the balisong-specific design knowledge that makes it flip the way a serious butterfly knife should.

    The blade is 154CM, the high-chromium stainless Pro-Tech has trusted across its automatic lineup for decades, ground into a 4.25" flat ground spear point with a satin finish — the same blade geometry as the Pro-Tech Godfather. It holds a working edge through sustained use, resists corrosion in daily carry, and sharpens readily on any ceramic or diamond medium.

    Black anodized aluminum channel handles run a bushing pivot system with zen pin construction for smooth, consistent flip action, finished with a short black deep-carry pocket clip for tip-up right-hand carry. It's built for experienced flippers who want a balisong held to Pro-Tech's manufacturing tolerances, and for collectors adding the Pro-Tech x Squid Industries collaboration to their catalog.

    What is a bushing pivot system?A bushing pivot uses a cylindrical bearing surface between the blade and handles instead of washers alone, giving the FlyFather 2 smooth, consistent rotation that holds up to repeated flipping without the pivot loosening over time.

    The Pro-Tech FlyFather 2 Buyer's Guide (2026)

    What makes this collaboration different, and what to know before buying a balisong.

    The Pro-Tech x Squid Industries Collaboration+

    The FlyFather 2 pairs two American manufacturers on a single platform: Pro-Tech contributes the machining precision and blade quality built in Placentia, California, while Squid Industries contributes the balisong-specific design knowledge that makes a butterfly knife flip the way it should.

    The result is a USA-made balisong built to a standard that production butterfly knives from either company alone could not reach.

    154CM Steel and Edge Care+

    154CM is a high-chromium stainless steel Pro-Tech has trusted across its automatic lineup for decades. It holds a working edge through sustained use, resists corrosion in daily carry environments, and sharpens readily on any ceramic or diamond medium.

    Spear Point vs. Tanto vs. Wharncliffe Blade Profiles+
    ProfileEdge ShapeStrength
    Spear PointSymmetrical curve to a centered tipBalanced slicing and piercing
    TantoAngular secondary edge to a reinforced pointTip strength for piercing and prying
    WharncliffeFlat edge, spine drops to a fine low tipControlled, precise slicing

    The FlyFather 2's flat ground spear point is the same blade geometry as the Pro-Tech Godfather, built for balanced performance rather than a specialized edge shape.

    Bushing Pivot vs. Washer Pivot Systems+

    A bushing pivot uses a cylindrical bearing surface between the blade and handles, rather than relying on washers alone, for smooth, consistent rotation that holds up to repeated flipping without the pivot loosening over time. The FlyFather 2 pairs its bushing system with zen pin construction for tuned, fluid flip performance.

    TipA well-tuned bushing pivot generally holds its action longer between adjustments than a basic washer pivot, which can be worth the tradeoff for flippers who practice often.
    Deep-Carry Pocket Clip and Carry Position+

    The FlyFather 2 carries a short black deep-carry pocket clip set for tip-up, right-hand carry, keeping the knife low in the pocket and the handles oriented for a quick draw into a flip-ready grip.

    Balisong Laws — Legal Considerations+

    Balisongs, also called butterfly knives, are restricted or banned outright in some states, counties, and cities in the United States, and some jurisdictions also restrict blade length or require a latch mechanism. Laws can also affect carry versus simple possession differently.

    Know Your Local LawsKnifeworks cannot provide legal advice on balisong ownership in your area. Laws differ by state, county, and city, and it is the buyer's responsibility to confirm what is legal where they live before purchasing. The American Knife & Tool Institute (akti.org) maintains state-by-state knife law summaries as a starting reference point.

    Pro-Tech FlyFather 2: Frequently Asked Questions

    Answers from Knifeworks' team on the Pro-Tech FlyFather 2.

    What is the Pro-Tech FlyFather 2?+

    It's a collaboration between Pro-Tech Knives and Squid Industries: a USA-made balisong that pairs Pro-Tech's machining precision with Squid Industries' balisong-specific design knowledge.

    What blade steel does the FlyFather 2 use?+

    It uses 154CM, a high-chromium stainless steel Pro-Tech has trusted across its automatic lineup for decades. It holds an edge well, resists corrosion, and sharpens readily.

    What is a bushing pivot system?+

    A bushing pivot uses a cylindrical bearing surface between the blade and handles instead of washers alone, giving the FlyFather 2 smooth, consistent rotation that holds up to repeated flipping.

    What's the difference between the FlyFather 2's spear point and a tanto or wharncliffe blade?+

    A spear point has a symmetrical curve to a centered tip for balanced slicing and piercing. A tanto trades that for a reinforced point built for harder use, while a wharncliffe trades it for a flat edge built for controlled slicing. The FlyFather 2 uses the same flat ground spear point as the Pro-Tech Godfather.

    Is the FlyFather 2 legal to own where I live?+

    It depends entirely on where you live. Balisong laws vary by state, county, and city, and Knifeworks cannot provide legal advice on what's permitted in your area. The American Knife & Tool Institute (akti.org) maintains state-by-state summaries as a starting reference point, but you should confirm current local law before purchasing.

    Where is the FlyFather 2 made?+

    It's made in the USA in Placentia, California, as a collaboration between Pro-Tech Knives and Squid Industries.

    What pocket clip comes on the FlyFather 2?+

    A short black deep-carry pocket clip set for tip-up, right-hand carry.

    Is this a live blade or a trainer?+

    The FlyFather 2 is a live blade, sharpened and intended for experienced flippers. Squid Industries sells separate unsharpened trainer models for practicing flips.
