Butterfly Trench Knife, 5-Inch Serrated Stainless Steel Blade, Removable Knuckle Guard, Latch Safety, 11-Inch Overall, Everyday Carry Self-Defense

There’s a certain type of person who doesn’t walk out the door without being prepared. Maybe you work late, walk to your car alone, or just believe — as I do — that hope is not a plan. If that’s you, the Butterfly Trench Knife is worth a hard look. It’s compact enough for everyday carry, built around a full 5-inch serrated stainless steel blade, and priced at under twenty dollars. That last part matters, because a tool you actually carry every day is worth ten tools sitting in a drawer. Who This Is Best For This knife is for the everyday carrier who wants a defensive edge — literally — without the bulk or cost of higher-end blades. It fits well for someone already comfortable with knives who wants a secondary carry piece, a camp or utility knife with defensive capability, or a dedicated EDC that won’t break the bank. It’s not a beginner’s tool. If you’ve never handled a balisong-style or knuckle-guard knife before, take time to get familiar with it before you rely on it. But if you know your way around an EDC blade, this one punches well above its price point. Decision Shortcut If you want a full-size serrated blade with an integrated knuckle guard, a secure latch safety, and a compact 11-inch overall profile — all under twenty dollars — this is the knife. It’s not a collector’s piece. It’s a working tool for people who take their personal readiness seriously without overthinking it. Key Features and Benefits 5-Inch Serrated Stainless Steel Blade — Serrations handle rope, webbing, and tough materials where a plain edge slows down. Stainless steel holds up to daily use and resists corrosion. Removable Knuckle Guard — Adds a layer of defensive utility when you need it, and removes cleanly when you don’t. Gives you options without locking you into one carry configuration. Latch Safety — Keeps the blade secured during carry so you’re not dealing with an accidental open in your bag or pocket. Simple, reliable, and something you’ll appreciate after the first week of carry. 11-Inch Overall Length — Substantial enough to be useful in a real-world situation, compact enough to carry without it becoming a burden. Under-$20 Price Point — At $19.95, this is a legitimate everyday carry knife at a price that makes it easy to say yes. You’re not gambling much, and the build quality holds up.

Blade laws vary by state, county, and city — blade length restrictions and carry laws differ significantly across the US. Check your local and state statutes before carrying this or any knife in public. Washington State, for example, has its own set of blade length and carry restrictions. When in doubt, check with your local law enforcement agency or a qualified attorney. Keep the blade clean and dry to maintain the stainless steel’s corrosion resistance. The latch safety should be tested periodically to confirm it’s seating properly. If you’ve been looking for a compact, affordable EDC knife with a little more defensive capability than a standard folding blade, this one is worth adding to your kit. At $19.95, the barrier to entry is low — and the confidence of being prepared is worth a lot more than that. Add it to your cart and see for yourself. Frequently Asked Questions Is this knife legal to carry in my state?Knife laws in the United States vary widely by state, city, and even county. Blade length limits, open versus concealed carry rules, and restrictions on certain knife styles all differ depending on where you live. Before carrying this knife in public, check your local ordinances and state statutes. When in doubt, a quick call to your local police non-emergency line can save you a lot of headaches. What does the knuckle guard actually do — and can I remove it?The knuckle guard wraps around the grip and provides a barrier between your hand and an attacker’s counter-force — it’s the same concept used in trench knives going back more than a century. It’s fully removable, so if you prefer a cleaner carry profile or the guard doesn’t suit your grip style, you can take it off without affecting the knife’s function. Most people try both and decide based on how they plan to carry it. How sharp does this come out of the box?The blade ships with a working edge — sharp enough for utility use right out of the box. Like any stainless steel blade at this price point, it may benefit from a light touch-up with a sharpening rod or stone after extended use. Serrated edges hold their working sharpness longer than plain edges but are slightly more involved to resharpen when the time comes. Is this a good choice for someone new to carrying a knife?I’d recommend getting comfortable with a simpler folding knife before moving to this style. The butterfly-style handle and knuckle guard add elements that benefit from some familiarity. If you already carry a knife regularly and want to step up to something with more defensive utility, this is a reasonable and affordable way to do it. If you’re brand new to EDC knives, start with the basics first.
