Revere Security OTF Automatic Knife, 3.5 Inch Single Edge Blade, 9 Inch Overall Length, Push Button Deployment, Premium EDC Self Defense Utility Knife

You cut open boxes. You break down zip ties. You open letters, trim loose threads, and occasionally, you carry something because you understand that being unprepared isn’t a strategy. Most knives ask you to choose between a tool you’ll actually use and one that’s ready if things go sideways. This one doesn’t make you choose.

Who this is best for: This knife is built for the everyday carry person who wants one blade doing double duty — the contractor breaking down materials on site, the delivery driver opening packages all day, the person who wants a defensive option that doesn’t look or feel like a novelty. If you’ve been carrying a folder and wishing it opened faster, or a double-edge OTF that’s more knife than you actually need for daily tasks, this is the practical middle ground.

Why this one: The single-edge blade is the detail that matters here. It’s sharpened on one side, which means better control for utility cuts — opening boxes, cutting cord, everyday tasks — without sacrificing the speed of true OTF deployment. Push the button, the blade’s out front and locked. Push it again, it retracts. No wrist flick, no two-handed opening, no fumbling when your hands are full or your adrenaline’s up.

Key Features & Benefits

• 3.5-inch single-edge blade — sized for control and legal carry in most jurisdictions, sharp enough for real cutting tasks
• 9-inch overall length — substantial presence in hand without being unwieldy in a pocket
• Push-button OTF deployment — blade extends and retracts instantly with one hand, front-to-back action
• Single-edge design — safer grip control for utility work compared to double-edge blades
• Solid lockup — blade locks firmly open and closed, no wobble, no surprises
• Pocket-ready size — built to actually carry, not sit in a drawer

Practical Details

OTF knives are legal in most U.S. states, but blade length and automatic-opening laws vary — check your local regulations before you carry. Keep the mechanism clean and lightly lubricated for smooth deployment over time. Comes with the knife; no case included, so plan your carry method accordingly.

If you’re ready for a knife that keeps up with your day and has your back when it counts, add this one to your cart. Browse the rest of our EDC and personal defense knives if you’re still comparing options.

FAQ

Is this knife legal to carry in my state?
OTF automatic knives are legal in most states, but some restrict blade length or automatic mechanisms. Check your state and local laws before carrying, especially if you’re crossing state lines regularly.

Is the single-edge blade good for both utility and self-defense?
Yes. The single edge gives you better control for everyday cutting tasks like opening boxes or cutting cord, while still providing a fast-deploying, effective option if you ever need it for defense.

How fast does the blade deploy?
One push of the button and the blade is fully extended and locked, no delay, no second motion needed. Pushing the button again retracts it just as fast.

Does it require maintenance?
Basic care goes a long way. Wipe the blade down after use, keep the mechanism free of debris, and apply a drop of lubricant occasionally to keep deployment smooth.
