Butterfly Trench Knife – 5-Inch Serrated Blade, Knuckle Guard

Some folks carry a knife because they like the look of it. That is fine. But the person who picks up the Butterfly Trench Knife is not shopping for decoration. They are the person who checks the locks, parks under the light, and wants something close that they can trust — a working tool with a real grip, a real blade, and a safety that actually holds. At 11 inches overall with a 5-inch serrated stainless steel blade and a removable knuckle guard, this knife is built for exactly that kind of person.

Who This Knife Is For

This is for the camper who needs to cut rope and wants hand protection when the work gets rough. It is for the person doing late-night rideshare shifts who keeps a bag within reach. It is for the hiker, the night-shift worker, the person who has looked at plain folding knives and thought they wanted something with a little more substance. If you carry with purpose and you want a blade that delivers real utility without a significant investment, this one is built for you.

Is It the Right Fit for You?

Choose It If You Want

• A butterfly-style handle that locks into a firm, stable grip when open
• A removable knuckle guard that protects your hand and improves control
• Serrated edge for cutting through rope, webbing, and tough materials
• A latch safety that keeps the knife closed until you decide otherwise

Consider Another Option If You Need

• A plain-edge blade for clean slicing tasks like food prep
• A more compact folding knife for pocket carry in tight spaces
• A fixed-blade sheath knife for heavy outdoor field use

Butterfly Trench Knife Features and Benefits

• 5-Inch Serrated Stainless Steel Blade: The serrated edge bites into rope, synthetic materials, and other tough surfaces where a plain edge loses its grip — real cutting ability when conditions are not ideal.
• Removable Knuckle Guard: Keeps your hand protected during close-contact use and gives you a more confident grip; remove it when you want a lower-profile carry option.
• Latch Safety Mechanism: Holds the knife securely closed during carry — it stays put until you open it intentionally, which matters when it is riding in a bag or pack alongside other gear.
• Butterfly-Style Handle: The balisong design deploys into a solid, stable grip; once open, it is not going anywhere in your hand.
• 11-Inch Overall Length: Enough reach to be genuinely useful without being unwieldy; this knife balances well and handles with confidence.
• Stainless Steel Handle: Durable construction throughout — the handle material holds up to regular use and does not add unnecessary weight.
• Under $20 Price Point: At $19.95, this is a knife that delivers practical utility without requiring you to make a significant investment before you know if it suits your carry habits.

Legal Notes

This knife is legal to purchase in many US states, but laws around blade length, butterfly-style handles, and carry method vary significantly by state, city, and county. Some jurisdictions have specific restrictions on balisong-style knives regardless of blade length. Check your local and state regulations before carrying this knife in public.

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 and measures 11 inches overall. That is a substantial, purposeful size — long enough to be genuinely useful in camp or utility situations, and the latch safety keeps it securely closed during carry so the length is not a handling concern.

Can the knuckle guard be removed from the Butterfly Trench Knife?

Yes. The knuckle guard is designed to be removable. Keep it on when you want the added hand protection and a more secure grip during use. Take it off when you want a cleaner, lower-profile look for carry. Either way, the blade and handle function the same.

How does the latch safety work?

The latch safety locks the butterfly handle closed so the knife does not open unintentionally during carry. It is a simple, reliable mechanism — engage it when you are storing or transporting the knife, and release it deliberately when you are ready to deploy. It is not complicated, and that is exactly the point.

Is the Butterfly Trench Knife legal to carry in my area?

Knife laws vary widely. Butterfly-style knives in particular are restricted or prohibited in some states, cities, and counties — sometimes regardless of blade length. Before you carry this knife in public, take a few minutes to look up your local ordinances. What is legal in one county may not be legal in the next one over. Your responsibility starts before you ever clip it to your bag.
