One of my favorite and top purchases in the EDC tool category.
I'm so glad I bought this. I LOVE this screwdriver/knife. They sell one that's larger and has scissors but honestly I've never used scissors that much and without them the size is perfect. If fits perfectly into the VIPERADE VE1 EDC Tool Pocket Organizer, or in my pocket. Seems sturdy. I tightened up the handle on my sliding glass door which takes a lot of torque to tighten and this accomplished that no problem. And if you leave it at a 90 degree angle to the handle instead of open fully you can squeeze even more torque out of it. (Not sure how much or if it's even recommended to use when not opened fully but it worked fine for me and still opens and closes as new and doesn't seem bent or distorted whatsoever. Good sturdy EDC screwdriver. Magnetically holds the bit in. Great color, great size, great usefulness, and great tool all around. I will order more as gifts in the future. Will update about durability and function after multiple uses. Probably my favorite purchase so far. I should mention the knife locks open but the screwdriver arm does NOT. Not a problem for me but maybe for others. It does fall into a divot or something when fully open so it stays open and you can hear it click in place so it doesn't just close from gravity or fall shut. Shipped on time. 5 stars all around.

Nice knife if you don't need a lot of extra fluff
I love that this knife has a good sized blade, locks into the handle, and comes with a useable screwdriver set. Those were the two features I mainly used from my old swiss army knife. The blade arrived sharp, and it fits fairly nicely in the had. I find the bottle opener almost impossible to deploy, there is no leverage to grab it to pull it out, and I can't see any way to change this. I don't really know if I'll ever use it, so that's not a big deal to me, but worth noting. Also, this is (obviously) not as comfortable to hold as a swiss army knife, since there are no sides covering the tools. It does allow it to have larger tools without feeling large in your pocket. Overall I'm very happy with it, and don't plan on replacing it any time soon.

Good minimalist multi-tool
I like my Gerber Armbar Slim Drive tool. It does exactly what any reasonable person would expect from such a tool. It is not a replacement for purpose-built screwdrivers. If you are building furniture, you should be using real tools. The driver on this tool is meant for light tasks (like tightening up drawer pulls, light switches, etc). It is a handy driver, and it works with any 1/4 inch bits including extensions. The driver does not lock, which seems to be a problem for a lot of people. I have not found that to be a problem yet, but I can see how that would be an improvement. The blade is excellent given the price range of this tool. It will meet the needs of any reasonable user, but will require occasional sharpening. I like the size and shape of the blade and find that it is handy for most cutting tasks. Mine came pretty sharp, but was razor sharp after a few strokes on a stone. The blade does lock via an internal spring liner. It is a little stiff right out of the box, but loosens up a bit with use. When comparing this against tools of similar size, price and toolset, such as a (Victorinox Tinker), this tool stacks up well. The blade and driver are superior to what you'll get with a Victorinox SAK. I recommend this tool, but Gerber could make some improvements. A locking driver would be the first thing I would improve. Second, I don't find the bottle opener useful, and it's awkward to use. I'd rather have the awl from the larger Armbar Drive.
G**!
Great Gerber quality knife!
After having read the reviews, I decided to purchase this knife/utility to use as an EDC. I received this knife and must say, I was impressed. Nice sturdy blade (not flimsy), easy to use Phillips bit as well as the slotted-head bit. It also contains a bottle opener. Unfortunately for me, my wife saw this knife/utility and decided to commandeer it for her own use! She said that she wanted it because there's always that time that we say "I wish I had a screwdriver to fix this or that," while out and about. PROS: Gerber quality, easy to use, perfect for an EDC CONS: None noted at the time of this review

This is an excellent pocket knife
I needed to replace a poorly manufactured Kershaw pocketknife that literally just fell apart when I dropped it onto a dirt driveway. I wanted a simple option of a quality blade with a flip out interchangeable bit that I can use around the farm. This knife met my needs and exceeded my expectations. When folded, It is much smaller than my old Kershaw, but the blade is just as long, and super sharp. So far I've cut cardboard, twine, rope, and briar canes with no signs of pulling the blade. THIS IS A GREAT KNIFE!

Um canivete robusto com lâmina grande, super afiada, acabamento primordial, braço de 5cm com chave de bit ¼ de polegada imantada que aceita bits universais pró estoque de qualquer marca. Pequena ferramenta com muita utilidade e da marca Gerber que já embarca qualidade no nome.

Es bastante bueno el filo de la navaja, ademas tiene bloqueo y se siente de excelente calidad, lo unico que le pongo de pero es que el desarmador no tiene bloqueo y la punta viene sin imantar (a algunos quiza no les guste).

Promete o que cumpre. Porém: - Lâmina super dura, difícil de abrir com uma mão; - Chave não permite muita força, se vc aplica força ela fecha. Apesar disso, pode receber bits 1/4 padrão, é uma alternativa ótima em um kit portátil (comprei com essa finalidade).
