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.

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!

Good, not great
It's been a good addition to my collection. It has become my EDC but that is because I work in an office and I find myself reaching for a screw driver much more than a knife these days. I'm used to a more robust knife and to be clear this is not built to be a beater. Knife is pretty thin but works perfectly fine to open boxes. A few notes: 1. You can't open the blade one handed. The half moon cut out to open the knife is too close to the pivot point. It could really benefit from moving the cut out or maybe a thumb stub. 2. There is no pocket clip. The knife is light but a little too big to put on my key chain. It would greatly benefit from a clip. 3. The driver is very useful but again, not something I'd really beat on. If the screw is on there good, you'll need a different tool. Also, the driver arm is a friction/detente lock only. Not a liner lock like the blade. Overall, not a bad knife for around the office. You're milage may vary.
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

Not worth the price
Ok I got this as a general purpose, 'wanted something besides my true Victorinox ones" and a little smaller than those and definitely not as bulky as a 'MacGuyver' multi-plier tool. However after having it and using it for 3 months here's the good and bad for this particular model since Gerber makes a few 'armbars now' some bigger and small ones like this one: *good size *nice having a double-sided bit/screwdriver "thus" the "in-line" armband name *blade is standard pocket knife and internal retention design. Decent functional. Though careful folding the leaf to fold it in if moving fast or tool is wet... Not so great... *Tweezers on this are useless. Flimsy and useless. So 4th tool on this is garbage *blade is okay, screwdriver is good. So that leaves advertised tool #3 the "bottle opener/other short flat head "tool." Its useless. Cause this is on such a pivot on one end and designed in such and inept way trying to sue the little quick 'flat screwdriver' part of this bottle opener part it keeps closing as you turn the tool. No good. Now this same tool as a bottle opener isnt great either because the angle of the lower jaw versus the upper part suffers from severe under-bite and the overtook is so thin that its just awkward to open a bottlecap with it. It works but you'll find you twist and bend the cap off instead of 'pop' it off. Real smooth with your armbar... Overall for the price this is a sad disappointment. Half the price great. But as Gerber keeps raising the price on this tool due to popularity its not worth it.

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).
