I reaaaaaaly like this knife the ceramic blade is dumb sharp and the quality of the knife is fantastic. It feels great in the hand. The spring assisted opening is the greatest. I haven’t found another razor knife that has that. It’s also nice and compact so it fits in the pocket well. My only concern was it accidentally opening in my pocket and losing the ability to reproduce. However I’ve been carrying it for a week now and it’s stays shut really well so no complaints from me.

UPDATE:I've bought 3 and going to get the U1 Pro as well. These knives are hands down the BEST I've used. It is so incredibly smooth and rock solid it's both a fidget toy and an indispensable EDC tool. I use it multiple times every day for literally everything, I can't imagine life without it. Best part is it's just a standard utility blade--I've gone with Workpro blades, which seem to hold up well and last a while.The quality you get for the price blows everything else out of the water.I took one to the beach and got fine sand everywhere in it, was able to disassemble completely and brush out all the sand, and I have to say the machining of parts is immaculate. Smooth as butter once reassembled.I can't say enough good things about this little knife.---------------------The action is super smooth and easy to flick open and closed straight out of the box. There is no play when opened and it locks up nicely.Materials seem high quality with proper machined hardware (unlike some cheap knives and tools).Comes with a Workpro blade.Comes with an extra little pry tool that you can use to turn the thumbscrew holding in the blade, which is pretty tight from factory.A 10/10 knife.

So overall, I am very pleased with this utility knife. I really like the crossbar lock or whatever it is they call it. It makes deploying one-handed very easy either with the thumb or with the crossbar lock. It’s a size fits into my pocket. The clip is very sturdy. It does not come loose from my pants. It Feels like a quality product to handle. The handle which is made of G 10 feels great in hand. I like the fact that I can use almost the entire edge of the blade when performing cutting tasks. My one complaint is the retention screw when I first received it was so tight that I thought I was gonna break it trying to loosen the blade. I ended up having to use , a pair of pliers to loosen up and I had to move it several times and put a little oil on there just to get the threads to work properly. After several days of doing this knife changes like a breeze and it holds the knife in place securely, but I no longer feel like I’m going to rub the skin off of my fingers trying to turn the knob. All in all a pocket friendly knife for everyday use. Now if I was doing hours of cutting boxes or other things or drywall I would definitely something something more heavy duty but for every day cutting task, this is one of the best utility knives I’ve ever used

This is a great little tool! I used it daily to open packages, and to break down boxes for recycling, as well as opening many other things like a stubborn package of bacon this evening.It clips into a pocket, and slides out and open instantly with the handy ambidextrous thumb knobs, and then one handed closes with the ambi slide lock and slips back into the pocket. I stuck a small braided paracord lanyard on it to make that even quicker.I recently moved into a new house, and of course ordered umpteen packages of furnishings and stuff needed. But early in that process of getting settled in, I misplaced this little tool, so I immediately ordered a second one! A few days later, my daughter found it at the bottom of a stack of cardboard boxes I had been breaking down! What a relief! So now I have two, in case I misplace it again!Pros::-small, fits hand and pocket easily-lightweight-rapid deployment for assaulting endless amazon boxes-blade quickly replaced with one small thumb screw-Looks cool with the CF scales!Cons:-so small it’s easy to misplace!I’ve always like olight’s flashlights—well engineered and reliable. Now their well-designed other EDC gear is another affordable daily pleasure.

Almost perfect! Been using utility knives for 15 years and this is my second favorite utility knife I've ever had. But they don't make my first favorite anymore lol. I love that almost the whole blade is exposed while most others only expose half the blade or less. I love how skinny it is, its not heavy or bulky and i barely even know if carrying it. The build quality is spectacular, it feels nice and solid and there is absolutely zero looseness or wobble in any part. The lockup is super smoothe and rock solid. The only things I would change are the length and the blade retention mechanism. I wish it was maybe an inch longer and I wish the blade retention was either a totally different mechanism or it was a standard hex head or flat head bolt, but I'm sure I could find a replacement if I really wanted to.
