MAXERI World's Smallest All Purpose Pocket Knife, Premium Heat Treated Stainless Steel Blade, Micro Concealable Minimalist Design, The Ideal EDC Knife

I bought this thinking it would replace my Buck keychain knife that I lost. You can tell the steel is great and the design "looks" great; however the function over form doesn't line up. Just opening the knife is a hassle. It seems like they didn't accurately dial in the resistance of pulling it open. It is anything but easy and that's frustrating. It locks fine - but then the other drawback: The unlocking mechanism is TERRIBLE! It has the typical design, but it puts your fingers at risk because it takes about 5 tries to accurately free the blade for closing. The size is fantastic and the blade works great. But they missed big time on the basics, quickly and easily opening and closing the knife.

First off the concept of this knife is great, however the blade never completely locks in place and mind the blade is VERY sharp, like sharpest knife I've ever owned. This is very hazardous as I've grazed my finger closing it a few times. I simply threw a washer in addition to the existing ones in the knife, it solved the problem efficiently. This blade as described before is sharp, it cuts through zip ties like butter, glides through plastic with no effort. I added it to my Keysmart keychain with some minor modifications. 4 stars for the blade lock not locking, over all a still great must have tool. I would love to see improvements to the design, and I absolutely would buy a bunch of these guys.

The knife is pretty neat and made of good quality material, very sharp out of the box, only a couple draw backs that are not apparent by the photographs in the add.1. There is a detente that holds the knife closed, there is little to get a hold of to open the knife, and makes it difficult to open.2. To close the knife there is a catch in front of the blade which places your fingers in front of the blade to close. It is also hard to press, so it takes great care to avoid getting your fingers into the blade when closing.If those items are something you can deal with, by all means grab one, it fits in your pocket and no more annoying than loose change.

Very durable. Has a nice heavy weight to it. Came already extremely sharp. Very easy to open and close quickly. As big as a normal house key, as seen in my photos. Only one con: the hole on it to attach to key ring is really tiny and does not fit normal or large key rings... I just happened to have a tiny, cheap ring on my set of keys already that I was able to use. Giving 5 stars anyway because it is clear that the manufacturer put the largest hole they possibly could on a knife that small of size. I love mine and use it daily.

It broke after spending one week on my keychain. Its not very well put together and can't take very much use before it completely falls apart. Would not recommend.

I am a woman and work in a field based position for a chemistry company in an urban area and had planned to use this for opening boxes, and thin plastic packages. It comes very sharp and and is easy for me to open and close. I attached it to my keychain for ease of access and it fits nicely and doesn't add any noticeable weight. I think for someone who doesn't open dozens of packages a day, it would be a good purchase but for myself, who for certain tasks will open dozens to hundreds of either packing boxes or small thin plastic packages, it wasn't a good fit and is already almost unusable when using the flat edge blade.I would recommend for the individual who receives occasional packages and wants something easy to break down a box that's easy to carry.Summary:PROS: easy to open and close, very sharp out of the box, light weight enough for keychainCONS: loses edge quickly if you're a very heavy userI haven't tried sharpening the blade, as it's so small and dulled so quickly I'm not sure that's worth the time for the frequency I'd need to sharpen, and it would be easier to switch to a keychain carry that has a replaceable/retractable razorblade.

It was definitely nice having a small knife blade at your side when you need it. I attached it to my keychain and the minimal size was unobtrusive. However, the knife itself didn't last long. After about a month of use, the thing fell apart. All that was left was the outer shell, still attached to my keychain. The blade portion was missing. I assume, after a very little amount of time, the screw that holds the blade came loose and somewhere, unbeknownst to me, the blade fell out.Also, the blade sharpness didn't last long even from normal use. I had to sharpen the blade once before it was lost within the month.

Awesome little knife. And I mean LITTLE! Visualize the knife from the pics and then mentally reduce it another 15%. It looks even smaller in person. Great for opening packages and small cutting duties. Seems very well made and carries in the pocket to the point you don't even notice. Bought a few of these as a follow up to give away to friends.
