Who This Knife Is For

This knife is built for collectors, martial arts practitioners, and everyday carriers who want a balisong-style blade with enhanced grip control. It suits the hobbyist refining flip technique, the outdoorsman who wants a serrated edge for utility tasks, and the self-defense student who appreciates a knuckle guard as an added layer of retention and hand protection during close-range scenarios.

Is It the Right Fit for You?

Choose It If You Want

• A balisong-style knife with a full 5-inch serrated cutting edge
• A removable knuckle guard for enhanced hand protection and grip
• A compact 11-inch overall platform that carries and stores cleanly
• A latch safety that keeps the blade secured when closed

Consider Another Option If You Need

• A fixed-blade knife with a sheath for rapid one-hand deployment
• A folding knife with a slimmer profile for deep-pocket carry
• A plain-edge blade optimized for push-cutting rather than sawing tasks

Butterfly Trench Knife Features and Benefits

• 5-Inch Serrated Stainless Steel Blade: The full-length serrated edge handles fibrous cutting tasks and provides aggressive bite on contact — stainless construction resists corrosion during extended carry.
• Removable Knuckle Guard: Adds a layer of hand protection and improves retention grip; remove it when a lower-profile carry is preferred.
• Balisong-Style Butterfly Handles: Stainless steel handles swing open and close around the blade tang, enabling practiced flip manipulation and secure blade containment when closed.
• Latch Safety: A positive latch mechanism locks the handles closed, preventing unintended opening during carry or storage.
• 11-Inch Overall Length: Provides enough handle real estate for a firm two-handle grip while remaining manageable for carry.
• All-Black Finish: Low-visibility black coloring on handles and blade reduces reflective signature in the field.
• Stainless Steel Handle Material: Durable, corrosion-resistant construction gives the handles solid weight and long service life.

Care

Wipe the stainless steel blade and handles dry after exposure to moisture. Periodically inspect the latch mechanism for wear and ensure the pivot pins remain tight. A light application of blade oil on the edge and pivot points will maintain smooth operation and edge integrity over time.

Legal Notes

Butterfly knives and knives with blades of this length are legal to own and carry in many US states, but a number of states, cities, and jurisdictions restrict balisong-style knives specifically or impose blade-length limits. Buyers should verify local laws before purchasing or carrying this knife.

Butterfly Trench Knife: Frequently Asked Questions

What is the blade length and overall length of the Butterfly Trench Knife?

The Butterfly Trench Knife features a 5-inch serrated stainless steel blade and measures 11 inches overall when open. The stainless steel handles enclose the blade fully when the latch is secured, keeping the closed profile clean and carry-ready.

Is the knuckle guard permanently attached to the Butterfly Trench Knife?

No. The knuckle guard is removable, which lets you configure the knife based on the task or carry situation. Attach it when you want additional hand protection and retention; remove it for a lower-profile grip or to reduce overall bulk.

How does the latch safety work?

A latch mechanism clips the two handles together when the knife is closed, preventing the blade from swinging open unintentionally. To open the knife, disengage the latch and manipulate the handles using standard balisong technique. The latch is a passive safety that adds a meaningful layer of security during storage and carry.

What kind of edge does the Butterfly Trench Knife have, and what is it best suited for?

The Butterfly Trench Knife carries a full serrated edge along the 5-inch blade. Serrated geometry excels at cutting rope, webbing, and fibrous materials where a plain edge would require more force. It is also well-suited for self-defense scenarios where aggressive edge contact is a priority.
