  • All-metal construction with stainless steel handle for durability and solid balance
  • Removable metal knuckle guard screws on and off without tools
  • Latch safety locks the knife closed when not in use
  • Available in Black, Plasma, and Stainless Steel finishes

All-Metal Build, Removable Knuckle Guard, 11 Inches of Butterfly Knife

Most butterfly knives prioritize flipping performance over structural weight. This one prioritizes build quality. The all-stainless-steel construction gives it a solidity that lighter balisongs don’t have — the handles don’t flex, the pivot doesn’t rattle, and the latch engages cleanly. The 5-inch serrated blade adds cutting functionality beyond what a plain-edge balisong typically offers. The knuckle guard is the notable feature: it screws onto the handle and comes off just as easily, so you’re not locked into one configuration.

Who This Butterfly Trench Knife Is For

This knife suits collectors who want a heavy-duty all-metal butterfly knife that stands apart from the lightweight trainers and flipping-focused balisongs that dominate the market. The 11-inch overall length and knuckle guard design give it a distinct profile that appeals to collectors interested in trench knife styling.

It also works for buyers who want a butterfly knife with real cutting utility — the serrated 5-inch blade handles rope, heavy material, and tough cutting tasks that a thin plain-edge blade struggles with. The removable knuckle guard means you can configure the knife to suit the task or your preference.

Is This the Right Choice for You?

Choose this butterfly trench knife if you want:

  • All-metal butterfly knife construction with substantial weight and durability
  • A serrated blade for cutting rope, heavy materials, or tough tasks
  • The option to add or remove a knuckle guard based on your preference

Consider something else if you need:

  • A lightweight butterfly knife optimized for smooth, fast flipping tricks
  • A plain-edge blade for precision cutting or food preparation tasks

How the Knuckle Guard and Latch System Work

The knuckle guard on this knife is a separate metal component that threads directly onto the handle using a screw attachment. This design means installation and removal take seconds — no tools required beyond your fingers. When attached, it wraps around the handle to protect the knuckles of your gripping hand. When removed, the handle returns to a standard butterfly configuration.

The latch safety is a standard balisong closing mechanism: a small latch on the handle locks the two halves together when the knife is folded closed, preventing accidental opening during storage or transport. Engage it every time you close the knife — it’s the simplest habit that prevents unintended deployment.

The serrated blade geometry is designed for aggressive cutting rather than slicing. Serrations grip and cut through fibrous, tough, or layered materials more effectively than plain edges in many utility scenarios, though they require a specialized sharpener to maintain the edge properly.

Frequently Asked Questions

Are butterfly knives legal to own and carry?

Butterfly knife legality varies significantly by state and local jurisdiction. Some states prohibit ownership outright, others restrict carry but allow ownership, and many permit both with no restrictions. California, Hawaii, and several other states have specific balisong laws. Always research your state and local ordinances before purchasing a butterfly knife. This product is sold for legal use only — verify your local laws before ordering.

How do I remove and reattach the knuckle guard?

The knuckle guard attaches to the handle via a screw fitting. To remove it, unscrew the attachment point — this typically requires only finger pressure or a coin for the initial loosening. To reattach, thread the guard back onto the handle and tighten until secure. The design is straightforward and doesn’t require specialized tools. Inspect the screw connection periodically to ensure it remains tight during use.

How do I sharpen a serrated blade?

Serrated blades require a tapered rod sharpener or a specialized serration sharpener — standard flat whetstones won’t work effectively on serrated edges. Work each individual serration separately by running the tapered rod through each scallop at a matching angle. Serrated blades generally hold their edge longer than plain-edge blades in fibrous cutting tasks, so sharpening frequency is lower. A ceramic rod sharpener works well for touch-ups between full sharpenings.

What is the difference between the three finish options?

Stainless Steel is the natural metal finish — silver-toned, standard appearance, and the easiest to inspect for wear or scratches. Black finish adds a surface coating that reduces reflectivity and gives the knife a tactical aesthetic — inspect periodically for coating wear at the blade edge and pivot points. Plasma finish refers to a color-treated surface process that produces an iridescent multi-tone effect on the metal. All three finish options share the same underlying all-stainless-steel construction and blade specifications.
