Butterfly Trench Knife – 5″ Serrated Blade, Knuckle Guard

Most carry knives force a choice: blade utility or hand protection. The Butterfly Trench Knife doesn’t ask you to choose. With a removable knuckle guard built into a balisong-style handle and a serrated stainless steel blade, this is a working knife designed around the realities of close-quarters use — not a display piece.

Who This Knife Is For

This knife is built for someone who wants a grip-integrated defensive option that doubles as a utility blade. It suits outdoors carry, camp use, or anyone who prefers a heavier, more substantial knife with hand coverage. If you train with balisong-style handles and want a blade that adds a knuckle guard to that familiar deployment, this fills that specific gap. It’s not a lightweight EDC folder — it’s a deliberate, purpose-driven tool.

Is It the Right Fit for You?

Choose It If You Want

• A butterfly-style knife with integrated grip protection
• A 5-inch serrated blade for cutting tasks that demand an aggressive edge
• A latch safety that keeps the knife closed and secure during carry
• A solid stainless steel handle that won’t flex under pressure

Consider Another Option If You Need

• A compact, lightweight folder for daily pocket carry
• A fixed-blade knife with a dedicated sheath system
• A plain-edge blade for precision cutting tasks

Butterfly Trench Knife Features and Benefits

• 5-inch serrated blade: Aggressive edge geometry handles rope, webbing, and hard material cuts where a plain edge drags
• Stainless steel construction: Both blade and handle material resist corrosion and hold up under outdoor and field conditions
• Removable knuckle guard: Adds hand coverage during use; removes when you want a cleaner profile
• Latch safety: Locks the handles closed during carry, preventing accidental deployment
• Butterfly-style handle: Counter-rotating handles allow practiced one-hand opening for users familiar with balisong mechanics
• 11-inch overall length: Full-size reach without the bulk of a fixed-blade
• Black finish: Low-reflectivity profile for low-visibility carry

Care and What’s Included

What’s in the Box

• Butterfly Trench Knife with removable knuckle guard

Care

Wipe the blade clean and dry after use to maintain the stainless steel edge. The latch mechanism should be checked periodically to confirm it engages firmly. The knuckle guard can be removed for cleaning or when a lower-profile carry option is preferred.

Legal Notes

Butterfly knives and knives with blades of this length are legal to own in many US states, but some states, cities, and venues restrict carry, concealment, or ownership of balisong-style knives entirely. Laws change. Check your local and state regulations before purchasing or carrying this knife.

Butterfly Trench Knife: Frequently Asked Questions

What is the blade length on the Butterfly Trench Knife?

The blade is 5 inches, serrated, and made from stainless steel. Overall, the knife measures 11 inches when open. That combination gives you meaningful reach and an aggressive cutting edge without stepping into fixed-blade territory. The serration pattern is suited to rope, cord, and material cuts where a plain edge requires more effort.

How does the latch safety work on this knife?

The latch clips onto the handle to keep the butterfly handles closed during carry. It’s a passive retention mechanism — you release it before opening, and re-engage it after closing. It won’t replace training or careful handling, but it prevents the handles from swinging open inadvertently in a bag or on a belt.

Is the knuckle guard permanently attached?

No. The knuckle guard is removable. When attached, it wraps the grip area and adds hand coverage during use. When removed, the handle profile is cleaner and lighter. Whether you run it with or without the guard is a matter of preference and how you intend to use the knife.

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

Balisong-style knives face restrictions in a number of US states and some municipalities, independent of blade length. Concealed carry of a blade this size may also be regulated separately from ownership. This isn’t something to guess at. Check your state statutes and any local ordinances before you carry this knife, and revisit those laws if you travel.
