Butterfly Trench Knife – 5-Inch Serrated Blade, 11 Inches Overall

Most knives make you choose between a utility blade and a defensive tool. The Butterfly Trench Knife doesn’t ask you to choose. The balisong-style handle flips open fast, the serrated blade handles real work, and the removable knuckle guard adds a layer of protection that most folders simply don’t offer. At 11 inches overall with a 5-inch blade, this is a serious piece of carry hardware — not a novelty.

Who This Knife Is For

This one is for the serious EDC carrier who wants more from a knife than a plain drop-point blade. It suits outdoors enthusiasts, preppers, and anyone building out a personal defense kit who wants a balisong-style design with a combat-oriented feature set. The knuckle guard sets it apart from standard folding knives — if you want that kind of grip protection in your carry rotation, this is built for it.

Is It the Right Fit for You?

Choose It If You Want

• A balisong-style knife with a 5-inch serrated blade ready for heavy use
• Removable knuckle guard for enhanced grip and hand protection
• A latch safety that keeps the blade secured when folded
• An all-black stainless steel build that handles field conditions

Consider Another Option If You Need

• A fixed-blade knife with a sheath for belt carry
• A shorter, more concealable folding knife for everyday pocket carry
• A plain-edge blade for precision cutting tasks

Butterfly Trench Knife Features and Benefits

• 5-Inch Serrated Blade: The serrated edge bites into rope, webbing, and tough materials where a plain edge would slip — built for real-world use, not display.
• Stainless Steel Construction: Both blade and handle are stainless steel, so the hardware resists corrosion and holds up in harsh conditions without special treatment.
• Removable Knuckle Guard: This is the feature that separates it from a standard balisong. The guard protects your hand during a firm grip — and comes off when you don’t need it.
• Latch Safety: The latch keeps the handles locked around the blade when closed, so it doesn’t open in a pack, pocket, or gear bag.
• 11-Inch Overall Length: At 11 inches open, you get a full, confident grip with serious reach — no compromises on handle length for the sake of compactness.
• Balisong-Style Handle: The butterfly opening mechanism is faster than a standard thumb-stud folder once you’re familiar with it — and it’s a distinct tactical advantage in the hands of someone who’s practiced with it.
• All-Black Finish: The blacked-out profile keeps a low visual signature and works with most gear setups without standing out.

Care and What’s Included

What’s in the Box

• Butterfly Trench Knife with removable knuckle guard

Care

Stainless steel is corrosion-resistant, but it’s not corrosion-proof. Wipe the blade clean after use, especially after exposure to moisture or salt air. Keep the latch mechanism clear of debris so it seats properly. A light oil on the pivot points periodically keeps the butterfly action smooth.

Legal Notes

Butterfly knives are legal to own and carry in many US states, but a number of states, counties, and municipalities restrict or prohibit balisong-style knives specifically — even where other folding knives are permitted. Laws on blade length and carry method (open vs. concealed) vary as well. Check your local and state regulations before purchasing or carrying this knife. Laws change, and it’s your responsibility to know what applies where you are.

Butterfly Trench Knife: Frequently Asked Questions

What is the blade length on the Butterfly Trench Knife?

The Butterfly Trench Knife has a 5-inch serrated stainless steel blade. Overall length when open is 11 inches. That puts it in full-size territory — this is not a compact or pocket-oriented blade. If you need something shorter for everyday pocket carry, a smaller folding knife may be a better fit.

Does the Butterfly Trench Knife come with a knuckle guard?

Yes. A removable knuckle guard is included. It mounts to the handle to protect your hand during a firm defensive grip and comes off when you want a cleaner profile. That kind of adaptability is uncommon in this price range and one of the defining features of this design.

How does the latch safety work?

The latch clips the two handles together when the knife is in the closed position, keeping the blade secured. It prevents accidental opening when the knife is stored in a bag or gear pack. Before opening, you disengage the latch — a standard balisong safety mechanism that most carriers get comfortable with quickly.

Is the Butterfly Trench Knife legal where I live?

Balisong knives face specific restrictions in several US states and localities — separate from the rules that apply to standard folding knives. Some jurisdictions ban them outright; others regulate blade length or carry method. Don’t assume that because standard folding knives are legal in your area, this one is too. Check your state and local laws before purchasing or carrying.
