Not Your Standard Butterfly Knife
Most butterfly knives are built for flipping — lightweight, balanced for tricks, and usually in the 8-9 inch range. This isn’t that. The butterfly trench knife is a heavier, more substantial piece that combines the butterfly opening mechanism with a knuckle guard design. It’s built for the person who appreciates the mechanical function of a butterfly knife but wants something with more presence and weight.
The removable knuckle guard is the defining feature — screw it on for the full trench knife configuration, or remove it for a standard butterfly knife setup. Two knives in one build.
Who This Knife Is For
Collectors who appreciate unique knife designs and want something that stands apart from conventional folders or standard butterfly knives. The trench knife aesthetic has historical significance, and this piece brings that design language into a butterfly format that’s genuinely uncommon.
Also suitable for butterfly knife enthusiasts who want a heavier, more substantial model in their collection. The all-metal construction and 11-inch length make this a different experience from typical lightweight flippers. It’s a display-worthy piece that also happens to be a functional knife.
Is This the Right Choice for You?
Choose this knife if you want:
- A unique collector’s piece that combines butterfly and trench knife design elements
- Heavy-duty all-metal construction with a 5-inch serrated blade
- The flexibility of a removable knuckle guard for two configurations
Consider something else if you need:
- A lightweight butterfly knife optimized for flipping tricks
- An everyday pocket carry knife — this is too large and heavy for that role
All Metal, No Compromise on Build
Every component on this knife is stainless steel. The blade, the handles, the knuckle guard — there’s no plastic, no rubber, no composite material anywhere. That adds weight (approximately 0.7 lbs total), but it also means the knife has a solidity you can feel the moment you pick it up. The 5-inch serrated blade is sharp and capable, with the serrations providing aggressive cutting ability on fibrous materials.
The butterfly mechanism uses a latch safety to secure the blade in the closed position. The pivots are designed to handle the rotational stress of opening and closing. The knuckle guard attaches to the handle via screws — easy to remove with basic tools if you prefer the knife without it, easy to reattach when you want the full trench knife look. Three finish options give you a choice: Black for a matte tactical appearance, Plasma for an iridescent color-shift effect, and Stainless Steel for the classic polished look.

Frequently Asked Questions
Are butterfly knives legal in my state?
Butterfly knives (also called balisongs) are restricted or outright prohibited in several U.S. states and many local jurisdictions. Some states allow ownership but restrict carry. Others ban them entirely. It is your responsibility to verify legality in your specific area before purchasing. We ship where legally permitted, but local enforcement and interpretation of knife laws can vary.
Can this knife be used for flipping tricks like a standard butterfly knife?
The butterfly mechanism is fully functional, so yes — it can be flipped. However, at 0.7 lbs with all-metal construction, it’s significantly heavier than typical trick-oriented butterfly knives. The weight changes the momentum and feel of flips. Most users find it more suited to basic open/close manipulation rather than advanced aerial tricks. Removing the knuckle guard reduces weight slightly and may improve flipping feel.
How do I remove or reattach the knuckle guard?
The knuckle guard is held in place by screws threaded into the handle. A standard Phillips or flathead screwdriver (depending on the screw type) is all you need. Unscrew to remove, screw back in to reattach. The threading is designed for repeated removal and reattachment without stripping, though applying excessive force with power tools is not recommended. Hand-tighten to a firm, secure fit.
What does the Plasma finish look like?
The Plasma finish creates an iridescent, color-shifting effect on the stainless steel surface — similar to what you see when oil sits on water. The colors shift depending on the angle and lighting, typically ranging through blues, purples, and golds. It’s achieved through a heat-treatment process on the steel and is purely cosmetic — it doesn’t affect blade performance or durability. It is the most visually distinctive of the three finish options.
