OKNIFE U1 Pro Multitool Folding Utility Knife with Folding Screwdriver, Quick Change Blade, Rail Lock & Pocket Clip for Men and Women (Carbon Fiber Overlay）

Having purchased the original version of this knife I had to try this one out. Now I’m a big fan of the Milwaukee fastback knives but they do tend to be a bit bulky for every day carry. As usual the build quality is wonderful on this. I purchased the carbon fiber version. I like the fact that the handle on this one is longer than the original, which was obviously needed to incorporate the bit driver. The bit driver itself takes smaller 4 mm bits, but this is no problem as I have a ton of those just laying around. I like the deployment of the bit driver as it uses a plunge lock so you can just flick it out or you can use your hand to open it. This is not necessarily as heavy duty as a Milwaukee, but it keeps all of the basics that you need in a lightweight form factor. The only thing that I miss from the Milwaukee is that you could store an extra blade on that one however that’s not really a big deal. I love how much cutting area you have available due to the blade locking mechanism. Some people don’t like how tight the little wheel can get, but seeing how as I typically have a Leatherman or some other type of tool with me I can easily tighten or loosen it. In my experience at least I have found that I don’t necessarily have to tighten it down with a tool as typically just hand tightening is enough to keep the blade in there without it rattling or coming loose. This is another wonderful tool from this company, and I plan on buying some more of these to have his back up and to give us gifts once they come back into stock out of all the utility knives I have this is probably my new favorite.

The original U1 was already well-regarded. In a KnifeCenter video comparison of 14 EDC utility knives, it tied for first. It was one-point shy of a perfect score because it had no extra tools.Well the U1 Pro addresses that by adding a locking 4mm bit driver. Which makes the U1 Pro the best compact EDC utility knife on the market. Yes, the Milwaukee Fastback has even more features. But it is nearly twice as heavy, and an inch longer. The pocket clip on the U1 Pro is deeper carry too.To me, the U1 Pro is perfect. It is very comfortable in the hand. Some observations:1. The action is great on the knife. On the screwdriver, I was able the thumb flick it once, but usually just a controlled open. Note: I had to oil the knife to get the action to work correctly on the screwdriver. Now it flips open and closed with the button.2. I was actually able to extend the blade by using the second top slot. There was no blade play, and the knife closed properly. I am not sure when having 98% of the blade would make a difference vs 85% of the blade, but it's possible.3. The bit is labeled PH0/SL3.5. I have this same bit from another Olight product, and the Phillips on the U1 Pro looks a touch bigger. Maybe closer to PH1. YMMV.4. My Hoto double-sided bits are the same size, and also magnetically retain in the U1 Pro.5. The Victorinox Cybertool bits are a little shorter, which allows the ball detent to engage and so they work too. I find the Victorinox bits to be a little larger than the Olight/Hoto bits. The main Vic bit is PH2/SL4, and it goes up to Torx 15 (vs T8 for Olight) and Hex 4 (vs Hex 2.5 for Olight).6. I could not shake the blade open, and I could not shake the screwdriver open. Once deployed, the blade lock up is excellent - zero blade play.7. I'll probably carry an Olight Opry as a complement to the U1 Pro in order to have access to a couple more double-sided bits. Some of the Opry models store 2 or 3 double-sided 4mm bits.

First and foremost the build quality is fantastic, both the slide lock to deploy the blade and the button lock for the screwdriver feel very premium, as well as the grip surface of the handle itself - and the donut pattern on the handle is of course incredible!I usually carry a Milwaukee Fastback and I took some pictures to show the size comparison - this knife is noticeably smaller and lighter, and without all of the contours and styling indents the fastback has, it definitely slides in and out of my pocket more easily.That being said, my one concern with this knife is that there is no locking mechanism to keep the blade locked in the handle - the slide lock only locks it while it's deployed, adding a small resistance in order to open the blade, but not a full-on locking action. I've had instances of knives opening in my pocket with this design, so I'd definitely love to see an addition of a closing lock as well.Another thing i noticed while cutting up cardboard was that while more of the blade is exposed, any cardboard that was being cut on the usually enclosed blade section would then continue on to hit the plate securing the blade in the U1, and would sort of just make it's way to the section of the blade with nothing above it. And in one instance the cardboard continued up the blade and began to loosen the blade locking screw - this may not be an issue if the screw is extremely tight via tightening with the included tool, but figured it was worth mentioning.Overall this knife feels incredibly solid and I could see it being a 10/10 EDC if you don't mind the lack of a closing lock, I'd give it at least 4.5 stars if I could!

Use it all the time at work. Great purchase

good utility knife and very good price. both the blade and driver are solid open or closed. accessing and locking either tool is easy, quick and smooth. the thumb screw for the blade may need a tool to loosen at times as it can be difficult to use just thumb and finger if overtightened slightly. high value utility knife

EDC utility knife. Using ceramic blades for even sharper cutting.

This is a great little utility knife. Well made and fitted, no blade play, and the gravity knife fidget factor is off the charts. The little screwdriver is a bonus, but it is little-#1phillips and a 1/8” wide flat blade driver combo. Comes with the little wrench shown for blade changes. Highly recommended.

Great box cutter. Quick and easy to use.
