    Butterfly Knife Buyer's Guide — Balisong History, Mechanism, and How to Choose

    The butterfly knife is one of the most culturally significant and mechanically distinctive folding knives ever made. This guide covers how balisongs work, the difference between live blades and trainers, legal considerations, construction quality differences, and how to choose the right model for your use. Click any topic to expand.

    How Butterfly Knives Work — The Balisong Mechanism Explained+

    A butterfly knife — properly called a balisong — has two counter-rotating handles connected to the blade's tang. Instead of a pivot like a conventional folding knife, the balisong uses a tang-pin or channel system that allows each handle to rotate independently around the blade:

    • The safe handle: When closed, this handle sits on the dull spine side of the blade. It is the handle that does not contact the sharp edge when the knife is closed — the "safe" side to grip without risk of the blade contacting fingers during manipulation.
    • The bite handle: The handle that, when closed, sits against the sharp edge of the blade. During manipulation flips, this is the handle that requires care — it is the one that can contact the edge if technique is improper.
    • The latch: A spring-loaded or friction latch on the safe handle keeps the knife closed. On quality balisongs, latch design significantly affects manipulation feel — a well-fitted latch that clips cleanly and releases crisply is a mark of quality construction.
    • The tang pin: A pin that stops the handle rotation at the fully open position, preventing over-rotation. Tang pin fit — whether it's a single pin, dual pins, or a channel stop — affects blade play and overall tightness of the open knife.

    Origins: The balisong originates in the Philippines, specifically the Batangas province on the island of Luzon, where it has been produced for centuries. The knife is central to Arnis and Eskrima — Filipino martial arts systems — and carries significant cultural identity. The name "balisong" derives from the Tagalog words for "broken horn," referring to the original handle material. Benchmade's butterfly knife line, the 87 Bali-Song series, is named directly for this heritage.

    Why Balisong Manipulation Is a Distinct Skill Opening a butterfly knife is not like opening any other folding knife — it requires learning specific flip techniques that develop over time. The manipulation skill is part of the appeal for a large segment of the market. Trainers with blunt practice blades exist specifically to allow this skill development safely. If you are new to balisongs, starting with a trainer before purchasing a live blade is the standard recommendation from practitioners at every level.
    ⚠️ Legal Notice — Butterfly Knives Butterfly (balisong) knives are restricted or prohibited in several US states and localities. Some jurisdictions classify them as switchblades; others have specific balisong statutes. Laws vary significantly — many states permit them freely; others restrict carry, possession, or both. It is the buyer's sole responsibility to verify that purchase, possession, and carry is legal in their specific jurisdiction before ordering. Knifeworks does not provide legal advice.

    Live Blade vs. Trainer Balisong — Which Should You Buy?＋

    The most important buying decision for anyone new to butterfly knives — and one that affects both safety and legality. Here is a complete comparison:


    		 Live Blade Balisong Trainer Balisong
    Blade Fully sharpened, functional blade — cuts as designed Blunt, unsharpened practice blade — shaped like a live blade but without a cutting edge
    Safety for Learning Higher risk during manipulation practice — contact with the bite handle can cause cuts Safe for extended flip practice — contact with the blade does not cut; the standard for learning
    Legal Status Subject to full butterfly knife legal restrictions in all jurisdictions May have different legal status in some jurisdictions — some states that restrict live balisongs permit trainers; always verify locally
    Best For Experienced practitioners; collectors; martial arts practitioners who know the handle well Beginners learning manipulation; anyone developing flip skills; practice without live blade risk
    Weight & Feel Full weight and balance of the production knife — the authentic manipulation experience Quality trainers match the weight and balance of the live blade version — practice transfers directly
    Price Generally higher — live blade steel and full knife construction Often lower — some trainer-specific designs; Benchmade trainers match live blade pricing
    The Standard Recommendation: Start With a Trainer Every serious balisong practitioner — regardless of experience level — recommends starting with a trainer. The flip techniques that make balisong manipulation satisfying take time to develop, and developing them with a live blade increases injury risk significantly. Once you can execute basic flips cleanly on a trainer, transitioning to a live blade of the same model is straightforward. Benchmade's 87T trainer is the direct trainer counterpart to their 87 Bali-Song — the weight and balance are identical.
    Butterfly Knife Construction — What Separates Quality from Budget+

    Balisong quality varies more dramatically than almost any other knife category. Here are the five construction elements that separate a quality balisong from a cheap one:

    • Handle channel and pivot tolerances: The handles must rotate around the blade tang smoothly and consistently, with minimal lateral play. Loose tolerances produce handle wobble — the most common complaint about budget balisongs. A quality balisong has snug, smooth handle rotation with no rattle.
    • Tang pin fit: The tang pin stops handle rotation at full open. In a quality balisong, the tang pin contacts the handle channel cleanly and firmly — there is a positive stop with minimal blade play when open. Cheap balisongs have sloppy tang pin fit that allows the blade to wobble when the knife is open.
    • Latch quality: The latch clips cleanly onto the safe handle when closed, releases crisply, and does not rattle during manipulation. A loose or poorly fitted latch undermines the entire manipulation experience.
    • Handle material: Quality balisongs use stainless steel, titanium, or G10 handles. Budget balisongs use cast zinc or pot metal — heavy, brittle, and prone to breaking at stress points under repeated manipulation cycles.
    • Blade steel: Entry-level balisongs use 420 stainless or equivalent — adequate for practice but mediocre edge retention. Mid-tier and premium balisongs use 440C, D2, or CPM-S35VN for meaningful cutting performance.
    Why Budget Balisongs Fail: The Handle Tolerance Problem The most common failure mode in cheap balisongs is handle channel wear — the pivot point loosens after even moderate use, producing increasing blade and handle wobble. Once a balisong develops significant handle play, the manipulation experience degrades and precise flips become inconsistent. Quality balisongs from Benchmade and Bear & Son maintain tight tolerances across thousands of flip cycles. This is the clearest argument for not starting with the cheapest option available.

    Butterfly Knives — Frequently Asked Questions

    Expert answers from the Knifeworks team on the most common butterfly knife questions — what they are, what's legal, trainers vs. live blades, how to choose, and how to care for your balisong.

    What is a butterfly knife?+

    A butterfly knife — called a balisong in the Philippines where it originates — is a folding knife with two counter-rotating handles connected to the blade's tang. Opening requires a specific flip manipulation where the handles rotate around the blade to reveal the edge. The knife locks open when both handles are aligned and the latch is engaged. The balisong has deep roots in Filipino culture and martial arts — Arnis and Eskrima — and has been produced in the Batangas province of Luzon for centuries. In the US market, butterfly knives are carried for collecting, skill practice, and martial arts training.

    Are butterfly knives legal?+

    Butterfly knife legality varies by state. They are legal to own and carry in many US states with no restrictions. However, several states — including California, Hawaii, New York, Wisconsin, and Kansas (for concealed carry) — restrict or prohibit butterfly knives. Some jurisdictions classify them as switchblades. Trainer balisongs with blunt practice blades may have different legal status in some states, though this is not universal.

    ⚠️ It is the buyer's sole responsibility to verify that purchase, possession, and carry is legal in their specific jurisdiction before ordering — for both live blade and trainer balisongs. Knifeworks does not provide legal advice. For state-by-state reference, visit akti.org.
    What is the difference between a butterfly knife trainer and a live blade?+

    A butterfly knife trainer has a blunt, unsharpened practice blade — shaped and weighted identically to the live blade version but without a cutting edge. Trainers are designed for learning and practicing flip manipulation safely, without risk of cutting yourself during the learning process. A live blade balisong has a fully sharpened functional blade. Quality trainers like the Benchmade 87T match the exact weight and balance of their live blade counterpart, so technique learned on the trainer transfers directly. The standard recommendation for all beginners is to start with a trainer regardless of experience with other knives.

    What is the best butterfly knife for beginners?+

    For beginners, the first purchase should be a trainer, not a live blade. The Benchmade 87T is the benchmark trainer — titanium handles, the exact weight and balance of the 87 Bali-Song live blade, and Benchmade quality that will survive extensive practice. If the Benchmade price point is a barrier, Bear & Son's trainer options deliver USA-made quality at a lower entry price. Both are significantly better starting points than unbranded imports, which typically have loose tolerances that develop slop quickly under practice-volume flip cycles.

    What is the best butterfly knife for experienced practitioners?+

    The Benchmade 87 Bali-Song is the production standard for experienced balisong practitioners — titanium handles, CPM-S30V or CPM-S35VN blade steel, precision CNC-machined tolerances, and Benchmade's LifeSharp lifetime sharpening warranty. It is the knife that defines what a production balisong is supposed to be. For practitioners who want USA-made quality at a more accessible price, Bear & Son's live blade models represent solid construction in the mid-price range. At Knifeworks, both are carried through authorized dealer channels with full manufacturer warranty.

    What is the safe handle and bite handle on a butterfly knife?+

    When a butterfly knife is closed, one handle rests against the dull spine of the blade — this is the safe handle. The other handle rests against the sharp edge — this is the bite handle. The names tell you the risk: gripping the bite handle during a flip that goes wrong can result in the blade contacting your fingers; gripping the safe handle keeps the blade spine between your hand and the edge. Learning to identify safe and bite handles by touch and position is one of the first skills in balisong manipulation. On most production balisongs, the bite handle is marked or differentiated — Benchmade uses a pin or machined feature to identify it.

    How do I maintain a butterfly knife?+

    Butterfly knife maintenance centers on the pivot channels and latch. Keep the pivot channels clean — lint and debris accumulate quickly under practice use and cause the handles to feel rough or sticky during manipulation. Clean with isopropyl alcohol applied to the pivot area, let dry fully, then apply a small amount of quality knife oil to the pivot points. The latch spring should be checked periodically — a fatigued latch spring will produce a loose-feeling latch that affects the manipulation experience. For the blade: wipe dry after use and oil periodically. On quality balisongs with CPM-S30V or CPM-S35VN, corrosion maintenance is minimal. Most production balisongs disassemble fully with standard Torx bits for deep cleaning.

    Why is the Benchmade 87 Bali-Song the benchmark butterfly knife?+

    The Benchmade 87 Bali-Song earns its benchmark status through the combination of titanium handle construction, precise CNC-machined pivot tolerances, premium blade steel (CPM-S30V and CPM-S35VN), and Benchmade's LifeSharp lifetime sharpening warranty — all in a production knife available through authorized dealers with full warranty support. The titanium handles are light, strong, and maintain tight tolerances across high flip-cycle counts without developing the slop that affects steel and brass channel designs over time. No other production balisong in the under-$400 range offers the same combination of material quality, tolerance, and warranty support.
