This is a heavy-built butterfly knife with a full-metal knuckle guard — which is the part that sets it apart from a standard balisong. The knuckle guard screws on and comes off if you don’t want it, so you’ve got options. Everything is metal, the blade is serrated and sharp, and it opens and closes the way a butterfly knife should.
- 5″ serrated stainless steel blade – sharp from the factory, serrations add cutting ability on fibrous materials
- Removable metal knuckle guard – screws onto the handle, comes off if you prefer a standard grip
- 11″ overall length – a full-size butterfly with real presence
- Stainless steel construction throughout – all metal build, no plastic or rubber anywhere
- Latch safety – standard butterfly latch keeps the blade locked when closed
A Butterfly Knife That Means Business
Most butterfly knives are one thing. This one adds a removable metal knuckle guard, which changes the feel considerably. It’s heavier and more substantial than a standard balisong — 0.7 lbs in an all-metal build — and the 5-inch serrated blade is not a decorative piece. If you’re looking for a serious butterfly knife that can also function as a knuckle weapon, this is built for that.
The knuckle guard screws on, which means it comes off just as easily if you want a cleaner look or lighter carry. Three finish options: Black, Plasma, and Stainless Steel.
Who This Butterfly Knife Is For
Collectors who want something with more character than a plain balisong will appreciate the knuckle guard and the three finish options. The all-metal construction and 11-inch overall length give it real weight and presence in hand.
Flipping enthusiasts should know upfront — this is heavier than a practice butterfly knife and the serrated blade is live. It’s built for use, not speed tricks. If you’re learning to flip, a trainer is a smarter starting point. If you know what you’re doing, this handles well.
Available in Black, Plasma, and Stainless Steel finishes — each one looks distinct enough that it’s worth picking based on what you actually want to look at.
Is This the Right Choice for You?
Choose this butterfly trench knife if you want:
- A full-size, all-metal butterfly knife with real weight and durability
- The knuckle guard feature for an added layer of utility
- A serrated blade that handles tough cutting tasks
- A collector piece with distinct finish options
Consider something else if you need:
- A lightweight balisong for speed flipping or practice — look at a trainer instead
- A compact pocket knife for everyday carry — 11 inches is not pocket-friendly
How It Actually Works
The butterfly (balisong) mechanism works the same way as any balisong — two handles that rotate around the blade’s tang and latch closed to lock the blade safely away. The latch keeps it secure when you’re not using it. Open it, and you’ve got a 5-inch serrated stainless steel blade ready to work.
The serrations run along the blade spine and make a noticeable difference when cutting rope, webbing, or other fibrous materials that a plain edge tends to drag on. The serrated edge also means you’re not sharpening this one on a flat stone — a ceramic rod or tapered sharpener handles serrations better.
The knuckle guard is the standout feature. It’s all metal, screws solidly onto the handle, and adds a meaningful amount of grip and hand protection. It’s also genuinely removable — this isn’t a marketing detail, it comes off and goes back on without any drama. Whether you run it with or without is up to you.

Frequently Asked Questions
Are butterfly knives legal to own and carry?
Laws on butterfly knives vary significantly by state and sometimes by city. Some states classify balisongs the same as switchblades and restrict or prohibit them. Others allow ownership but restrict concealed carry. A few have no restrictions at all. Before purchasing or carrying this knife, check the specific laws in your state and municipality — it’s worth a five-minute search.
How difficult is the knuckle guard to remove?
It screws on and off, so you’ll need a screwdriver to do it cleanly. It’s not a tool-free swap, but it’s not complicated either. Once off, the handle has a standard grip profile. Most people pick one configuration and leave it. The hardware is standard enough that a basic Phillips screwdriver handles it.
Is this knife suitable for learning butterfly knife tricks?
It’ll work for someone who already knows how to flip, but it’s heavier than a dedicated flipping knife and the blade is live and serrated. Beginners learning balisong manipulation are much better served by a practice trainer — a dull-bladed version designed for that purpose — before moving to a knife like this one. The weight and size make it slower to manipulate than a lighter flipping knife.
How do I sharpen a serrated blade?
Serrated blades need a tapered ceramic or diamond rod sharpener rather than a flat whetstone. You work each serration individually, matching the angle of the bevel. It takes a bit longer than sharpening a plain edge, but serrations also tend to stay sharper longer in everyday use because the points maintain their geometry well. If that sounds like too much work, a plain-edge knife is an easier maintenance proposition.
