"I really wanted a knife first multi tool and was excited for this one but the tools are so hard to open I need something to pry them. I end up not carrying it due to that."
"Nice knife but over two weeks to be delivered then the small screw driver broke on the first time I used it. So now I have to send it back which I’m guessing won’t be a quick process. Looks like it’s not available on the website anymore. I’ve had other Leathermans in the past which have all been great. Maybe I got a lemon, if there is such a thing."
"I have a bunch of Leatherman tools over the years and love there products. Decent knife but for the price you might as well buy a Wave multitool. They do make excellent tools."
"I was eagerly looking forward to receiving my K4. I'm a pretty die hard Leatherman fan given that I own 6 of their multitools. The Free K4 however, was no FREE. Had to employ a needle nose pliers to get any of the tools other than the knife to open. Even after opening and closing them a number of times, they still require assistance getting to open. On top of that, the spring on the little scissors does not work. When I received it, I assumed it would work and threw the packaging away. Can't return it."
"I bought it to use in my work, I loved it is a very strong knife, I love the combination of tools and the very useful scissors in this tool. Buy the Free K4 first for my job and at a week I ordered the FREE T4 to use when I'm not at work, perfect size, weight and tool combination for EDC, Excellent quality I'm very happy and satisfied, it's like a SAK but with steroids 😂 and made in USA lol, I like it 💯🔥👍 great job 👏 Leatherman ⭐️⭐️⭐️⭐️⭐️."
"The Leatherman K4 is a good overall carry tool. The handle is shaped in such a way as to allow the knife to be easily opened and used, while also allowing the tools to be extracted from and returned to the butt single handedly. If the T2/4 series makes the knife feel like an afterthought, the K series is built around bringing a large blade to bear. Having said that this tool was built around the blade, I find the other tools to be the real stars of this assembly. The scissors are effective, though mine often stick closed when initially deployed, and aren't the absolute best multitool scissors I've seen. They can cut a zip tie if pressed. The awl is a tool I've always disregarded on pocket knives, but the awl on this knife has won me over. It drills with ease through materials that it is unsafe to dig a knife blade into. It was putting a hole in a pop bottle cap with ease that most surprised me. The Phillips head/bottle opener Is sufficient. It does better than many flat form Phillips heads do, but won't beat a true Phillips head. The flathead/box opener is a robust prying head, and the box opener unsheathes Romex with authority. Locks on the tools and knife are the same style, and appear both elegantly simple and robust. I tested the lock on the screw driver with as much force as I felt was safe, and it did not fail. I would be interested in seeing data on how strong this lock is. The aluminum scales are durable, and tapered to fit the hand well when cutting. Now, the knife blade. The blade is effective. It's big. For a knife I'm going to carry in situations where I don't have access to a screwdriver, scissors, or a drill, the K4 is big. To accommodate the blade, the entire tool takes up a fair bit of space in the pocket, (far more than the old Crater C33T that also had a flathead and Phillips) and has a large enough blade to draw eyebrows in polite company. When I was a teenager I loved blades this size, but as an adult, I've grown to appreciate a shorter blade profile. I am considering shortening this knife blade. Only the inability to buy a replacement blades as prevented me trying my hand at a modification. Overall, I like the K4, though I feel a bit of shortening would make it more practical."
"I’ve had my Free K4 since it debuted, and it usually one of my go-to knives for medium to heavy duty tasks. It holds an edge pretty well, it is easy to sharpen, and thus far has required little to no maintenance!"
"Fits in pocket or backpack with ease. Easy open and close tools, worth the investment when camping."
"I bought the Leatherman Free K4 with pretty mild expectations. With that said, a couple months later, after carrying it almost exclusively, I can honestly say it’s one of the best all in one options on the market. The Free K4 grows on you rather quickly. I found myself searching for something that would really fit my EDC needs, because a knife alone just doesn’t do the job. I realized that during my day to day a knife is something that I needed about 30-40 percent of the time, the other 60-70 percent of the time I need a screwdriver, scissors, pry bar, or one of the other tools conveniently located on the Free K4. The implements being all constructed from 420HC works out good, because if you’re like me, you have invested in sharpening supplies and taught yourself the art. I can take the blade and run it over my ceramic hone and then hit it on the leather strop and it’s right back to hair popping sharp in just a few minutes. If you spend 5-10 minutes every couple of weeks and touch the blade up it will last you a long time. The biggest complaint I see is the weight but that doesn’t make sense to me. People will carry a full size multi tool without hesitation but expect a knife with a whole cash of tools on the back side of it to be a feather. If you want options then you compromise on weight. It’s still only 5. 5oz and is more than manageable. The Free K4 is what I carry full time now and it has retired a drawer full of knives from Benchmade, Spyderco, Hogue, and many more. I highly recommend this product to the guy or gal that has come to the realization that a knife alone doesn’t really meet your needs."
"This tool has been through it, after being dunked in paint thinner and oil based paint, it continues to open and close just like the day it was brand new!"
