OKNIFE U1 Pro Folding Utility Knife with Folding Screwdriver, Quick Change Blade, Rail Lock and Pocket Clip for Men and Women (Donut Type)

The OKnife U1 Pro has won out as my every day carry. The thumb stud is eminently flickable, and I am generally a fan of the "tool-less" clip for the blade that both reveals more of the razor and is fairly easy to change (it's not really tool-less, as you'll almost certainly want to use the included lever to really tighten it all the way down, but in a pinch you could probably get away with hand-tightening). Personally, I appreciate the simplicity of carrying a utility-blade knife. It's (usually) not as stylish as a "real" knife, but I carry my knife to use it -- being able to keep it sharp with a low-effort blade change and not needing to worry about "ruining" the blade means I use it for everything (except food). The addition of the bit driver is what makes this my top EDC choice. I also carry the Oknife 12-piece bit set (which I would strongly recommend if you purchase this knife). This combination allows me to work with a lot of fastener use-cases without having to go get my tools, and removing this hurdle often means I fix something when I see it vs. making a mental note to do it later. The bits aren't full-size like the Milwaukee Fastback, almost certainly an inspiration for this knife -- but the Oknife is also significantly less bulky. The bits aren't always the exactly what I would want for the problem at hand but generally are enough for the kind of small tasks that you would want to do without a full toolbox. You get some nice variety with the separately-sold 12 bit pack (including a pencil!) and I like knowing I'm covered there, but you could probably get away without it as I use the included philips/flat 90% of the time (allen/hex bit is the other one I'll generally use). I like to run a ceramic blade in mine which seems to hold it's sharpness for near forever (although chips easy) -- I recommend giving them a shot. The only thing I'd love to see is maybe a flipper tab/push-button release for the utility blade (I really liked this on my Ti Oknife U1), and possibly some ultra-lightweight scales (carbon or al? I would love to minimize my pocket weight). The only thing that could beat this for me is a knife with the same features but a bit more style to it -- and so far, that doesn't exist.

Una herramienta excelentemente diseñada, hay pocas herramientas para este tipo de navajas que aprovechen el filo de la mejor manera además de que es mucho más difícil que se mande a la fregada el filo tiene muy buena sensación y es práctica además de resistente

I have carried this knife as my EDC for around a year and a half at this point. It has been a great blade, but it’s got some pretty big design flaws that have led me to look elsewhere. There is a metal pin near the hinge that moves side to side, which makes the fluid motion of opening it not so fluid. You have to find a tiny flathead to push the pin back to center before the opening mechanism is smith again. Another design flaw is the blade lock. The screw that holds in the blade is probably the worst thing about it. You will never get a tight hold on the blade using just your fingers to tighten the screw. Along with that, anything you cut will just turn it loose again anyway. A few things I truly like, the thumb stud and opening mechanism are very smooth (when working properly) and the deep carry pocket clip keeps it far out of sight. The scales feel very high quality and even after a year and a half, no color fading has occurred. It has been a decent enough knife for me to hold on to it for this long. The constant tightening of the blade before every use is the biggest reason I am abandoning this design.

Got this as a B-day gift for my wife. She loves it. She now has a slim multi-tool that is easy to carry and always super sharp. I also got her the OKNIFE MBS1 4mm Hex Bit Screwdriver Set, giving her a full set of screwdrivers in her pocket.

It’s adorable. Has lots of blade usage. I dropped this at one of our building and found it a month later in the same shape I lost it. It’s got great durability pretty easy to take apart the locking system on it makes it easy ro open and close so never really a reason to leave open can fold with one hand
