OKNIFE Otacle U1 Folding Pocket Utility Knife, Quick Change Box Cutter with Rail Lock, EDC Razor Knife with Pocket Clip for Office, Factory (Doughnut)

I’ve been carrying the OKNIFE Otacle U1 for about three months now, and I’m genuinely impressed with this folding utility knife. It has quickly become my go-to EDC tool, and here’s why I think it deserves five stars. The first thing you notice when you pick up the Otacle U1 is the solid construction. The aluminum handle feels substantial without being heavy, and the fit and finish are excellent. There’s no blade play whatsoever, and the tolerances are tight. The ergonomics are well thought out, with the handle providing a comfortable grip for extended use. The pocket clip is positioned perfectly and has just the right amount of tension to keep the knife secure without making it difficult to remove. The D2 steel blade holds an edge remarkably well. I’ve used this knife for everything from opening packages to breaking down cardboard boxes, cutting rope, and general utility tasks around the house and workshop. Even after weeks of use, the blade remains sharp enough for clean cuts. When it does need sharpening, the D2 steel responds well and takes a nice edge. The flipper mechanism is smooth and satisfying. After a short break-in period, the knife deploys with a crisp action that feels reliable every time. The liner lock engages solidly and inspires confidence during use. I’ve never had any concerns about the blade closing unexpectedly, even during harder cutting tasks. The ingenious utility blade holder feature sets this knife apart from standard folders. Being able to swap in a fresh utility blade for particularly tough or messy jobs is incredibly convenient. This dual functionality means I’m carrying essentially two tools in one compact package. For the price point, the OKNIFE Otacle U1 delivers exceptional value. The quality of materials and construction rivals knives that cost significantly more. It’s clear that OKNIFE put serious thought into creating a practical, well-made tool rather than just another budget folder. The OKNIFE Otacle U1 has earned a permanent spot in my pocket. It’s reliable, well-made, comfortable to use, and genuinely practical for everyday tasks. Whether you’re looking for your first quality folding knife or adding to an existing collection, I highly recommend giving the Otacle U1 serious consideration. You won’t be disappointed.​​​​​​​​​​​​​​​​

This thing is small, extraordinarily well built, and has a tip up clip. Super easy to flick open, before oiling, and secure mounting of the blades. The only (very minor) drawback is that you need pliers to grip the blade change knob, but I will take that, as it is very secure in holding the blade spine, and allowing full use of the edge. Great pocketknife! As an update, included is a piece of 550 cord, and the little tool pictured.... it is tucked away in the box and I missed it previously..... if you tue the lanyard on, you have a blade change wrench on the cord......

This is the coolest utility knife I’ve ever had. I was sold immediately when I saw they came out with this in the green micarta scales. It’s an awesome looking knife. It’s a smaller knife and fits perfectly in the 5th coin pocket on pants. It fits very well in the hand especially for someone like me with small hands. It’s very functional especially since they designed it to give you access to almost all of the cutting edge. They give you some parachord and a multitool in the box. The parachord is the perfect amount to make a snake knot lanyard which I recommend doing to help pull the knife out of the pocket because without it sometimes it could be a little difficult. I highly recommend keeping the multitool with you when carrying the knife. I keep mine on my keychain. The tool has a cutout that is a wrench for tightening and loosening the blade retention screw. You can use your fingers if you wanted but with the tool you can tighten it enough to where it will not back out over time with use. I have spent hours flicking open and closing the knife and have had no issues with the screw backing out. The knife is running on ball bearings so it’s very smooth and snappy when opening and closing which also makes it fidget friendly. I have no negative things to say about this product. Just get you one. It’s 100% worth every penny.

The pivot is strange. It's simultaneously crunchy, and very free turning. There's no resistance to it swinging around at all, but it does not feel smooth. The screw to lock the blade down is tough to get tight enough by hand, I use small pliers. The spine being thicker than the blade is unavoidable for a utility blade holder like this, and it does have the drawback that the spine can snag a bit when cutting through sheets (like cardboard) Those are my only gripes. Other than that, it's a solid little inexpensive edc knife. There's very little to no blade play when locked. It's very easy to operate one-handed. Exposing so much of a utility blade is an excellent idea and works great. It's thin and light. Definitely recommended.

I absolutely love this thing. It's everything I didn't know I needed in a utility knife. It exposes the maximum blade length, it holds the blade completely securely with no play, it fits well in my hand, it has butter smooth opening and closing action, a very nice open/close locking mechanism, it frankly looks cool... it's fantastic. It's like a decent proper knife with the features to match, but it's a utility knife with a replaceable blade. The only thing I don't like about it is that the screw which holds the blade so securely could be prone to over-tightening / stripping and requires a tool (either the one that is included, or a set of pliers to grip the tightening screw securely). Maybe it's not necessary to crank it down so hard, but I'm just matching the torque that I had to undo from the factory. When I didn't go so hard on it, the blade did seem like it could be prone to some movement (but still no more, and far less than the crap you get at the big box stores from "name brands" which just rattle around in the housing). Still, it's the one thing that isn't perfect.

My only long term concern is the screw down blade holder. The screw is tiny. Only time will tell if the threads hold up or it gets lost etc. Other than that, this is just perfect for opening packages at home and keeping staple scratches and glue off your main blade. Great quality and action. Fits in the change/watch pocket of my jeans. Not designed to replace regular box cutters in a work environment, but perfect for edc box, package, etc chores around the house. Comes with a small multi tool and paracord to tie a lanyard which I did. The macarta is awesome.

The OKNIFE Otacle U1 Folding Pocket Utility Knife is a solid, practical tool for everyday cutting tasks. Its compact size makes it easy to carry in your pocket, and the aluminum alloy body feels sturdy without being heavy. The real standout feature is the quick-change blade system—just slide it out and pop in a new one, no tools needed, which is a huge time-saver. The blade works smoothly on cardboard, plastic, and other common materials, giving clean, precise cuts every time. The rail lock keeps the blade secure, so there’s no worry about it slipping during use. The folding design also adds an extra layer of safety when it’s not in use. Overall, it’s a great knife for cutting tasks, offering good value, ease of use, and solid performance. It's a reliable choice.

Exactly what I was looking for, locks the blade in well. Hides in the pocket and opens easily one handed. Micarta wears in well and grips even when the hands are a bit wet. Takes all blades that I’ve tried, Lenox, Stanley and dewalt all fit. Just don’t over tighten the set screw or it will loosen up after you open it. Thankfully if you over tighten it won’t strip out
