This is a heavy-duty butterfly knife built from all-metal construction with a removable knuckle guard — the kind of design detail that separates a purpose-built tool from something that just looks the part. The blade is sharp, the serration is functional, and the knuckle guard screws on and off depending on how you want to carry it. Eleven inches overall, solid feel in the hand.

  • All-metal construction throughout — no plastic, no flex
  • 5-inch serrated blade with sharp edge and tapered point
  • Metal knuckle guard screws onto handle and is removable for standard carry
  • Latch safety locks the knife closed when not in use
  • 11-inch overall length, available in Black, Plasma, and Stainless Steel

A Butterfly Knife Built to Actually Hold Up

Most butterfly knives you’ll find at this price point have some plastic somewhere — in the handles, the latch, the pivot hardware. This one doesn’t. It’s all metal, which means it has the weight and rigidity you’d expect from a working tool rather than a novelty. The serrated blade adds utility, and the removable knuckle guard is a straightforward design choice that gives you options depending on how you intend to use it.

Who This Butterfly Knife Is For

Collectors who want a distinctive piece with more visual interest than a standard balisong. The trench knife design and knuckle guard combination is a specific aesthetic that a lot of people look for, and this one delivers it in three finish options — Black, Plasma, and Stainless Steel — so there’s a version for different display preferences.

Dealers and resellers will find this moves well at gun shows, flea markets, and knife-focused events. It has immediate visual appeal on a display table, comes in multiple color variants, and the all-metal construction lets you speak to the build quality with confidence. Buyers who pick it up can feel the difference from lighter alternatives at a glance.

Is This the Right Choice for You?

Choose this butterfly knife if you want:

  • All-metal construction with no plastic components
  • A trench knife style with functional removable knuckle guard
  • A serrated blade with real cutting utility
  • A collectible or display piece with strong visual presence

Consider something else if you need:

  • A lighter, slimmer balisong optimized for flipping practice — the knuckle guard adds bulk
  • A straight-back blade without serration for specific cutting tasks

Construction and Features Worth Knowing

The all-metal build gives this knife a solidity that shows up immediately when you handle it. The blade runs five inches with serration along the spine, which adds utility for cutting rope, webbing, or other materials where a plain edge would require more effort. The tip is tapered and pointed.

The knuckle guard is the feature that makes this a trench knife rather than a standard balisong. It’s screwed onto the handle, which means you can remove it if you want a cleaner profile for carry or display. That’s a practical design choice — you’re not locked into one configuration. The latch keeps the blade secured when the knife is closed, which is standard for butterfly knives and means you’re not worrying about accidental opening during transport or storage.

Three finish options give buyers or resellers some variety: Black for a tactical look, Stainless Steel for a clean traditional appearance, and Plasma for something more visually distinctive. At eleven inches overall, it’s a full-size knife with real presence.

Frequently Asked Questions

Can the knuckle guard be removed permanently, or does it need to be reattached to use the knife?

The knuckle guard is attached with screws and can be removed or reattached as you prefer. The knife functions as a standard butterfly knife with the latch safety whether the guard is on or off. Removing it gives you a slimmer profile, which some people prefer for everyday carry or simpler display. Reattaching it gives you the full trench knife configuration. Either way, the core mechanism of the knife is unchanged.

Is this suitable for balisong flipping practice?

The all-metal construction and 11-inch overall length make this a heavier, more substantial knife than what most people use for flipping practice. Standard balisong trainers and lighter practice knives are better suited for developing flip techniques. This knife is better suited as a collector’s piece or a functional utility knife where the trench knife design and knuckle guard are the draw.

What does the latch safety do and how does it work?

The latch is a spring-loaded clip that locks the two handle scales together when the knife is in the closed position, securing the blade inside the handles. It prevents accidental opening during storage or transport. To open the knife, you disengage the latch and use the standard butterfly opening motion. This is a standard feature on quality butterfly knives and is a basic safety consideration for carry and storage.

Are butterfly knives legal to own and carry?

Butterfly knife laws vary significantly by state, county, and city. Some jurisdictions restrict ownership, carry, or sale of balisong-style knives. Before purchasing, it’s your responsibility to check the laws in your specific location. This applies both to individual buyers and to dealers reselling these knives at local events. When in doubt, consult your local laws or a legal professional.
