SOG Multi-Tool Pliers PowerAssist Pocket Knife with 16 Lightweight Specialty Tools and EDC Sheath (B66N-CP), Black

I carry this tool every day and love it. I find myself using it on a regular basis and it always performs. I am a carpenter/contractor which means I already own many full sized versions of the tools included in this piece, but that doesn't mean I have them on my person all the time. If I'm on a job and need to make a quick cut, crimp, turn of a bolt or screw it used to mean wearing my 30lb framers belt all day, or stopping to go the my tool bag or truck. Now, just a flip of the velcro flap on my belt and I'm on to the next thing, saving time and money. This tool has more than paid for itself for this reason alone. The case is very heavy nylon which holds its shape to allow easy deployment and insertion. Also the open sides on the top and bottom prevent debris build up with is very beneficial to me (I pretty much pour saw dust out of my pockets at the end of the day). The compound action of the pliers is amazing. You can cut, crimp, or pinch anything with ease which is rare for most multi tools because of their size and shape. The multiple screwdriving bits are sturdy and effective with the piano key type lockup allowing you to put sufficient force on them without having fear of the bit closing on your fingers or damaging finished surfaces. The 2 blades are very useful as well, and for some may suffice as an EDC set. Though I still carry a dedicated knife for that purpose, it never hurts to have options. I tend to use these blades for tasks that could result in damage to a blade I wouldn't want my pocket knife going through. They both hold an edge very well and sharpen easily. I usually only have to touch them up every week or so. Which brings me to another great design feature of this tool. SOG carries a full line of replacement tools/blades so the fear of breaking a piece and rendering a $60 tool useless is put to rest, as well as giving the option for customization. Some may have an issue with the weight, but between all the other items I have on me 24/7, I don't notice it at all, as well as it being a testimate to its strength and durability. If I could think of any con it would be the sliding locks for the 2 blades. They have a very short throw allowing them to accidentally engage. I noticed this the first day I owned this tool and quickly fixed it with a single drop of super glue to permanently lock them in the off position, as I also feel they're unnecessary with the sprung tension on the blades. I've never had one open on my accidentally. I love this thing and know it will last for years to come, through all the use and abuse I have planned for it.

I've been in and around construction/maintenance for over 20 years and just recently realized the value of a good multi-tool at your side. The ones I usually see are cheaply made or were more trouble to use to be of any benefit. Then I picked up a beat-up SOG Powerlock at a garage sale for 10 bucks. Not realizing what I had it sat for months unused until I did some research on SOG products. I ordered a sheath for it from SOG and it became indispensable. You really do use it more than you think you would. Then I saw the Power Assist! Basically the same as the Powerlock but with the 2 assisted opening blades which are truly awesome and fun to work with. It's truly a one-handed tool as far as the blades and the pliers are concerned. And let's face it the pliers are what most people will use the most. A lot has been said about the compound leverage gears and it's all true. I played with a Leathermen SURGE at a retailer alongside a power Assist before I bought mine. The Surge was VERY heavy and took a lot just to open up the pliers. it was very stiff. Perhaps it needed a little breaking in. The Power Assist by comparison opens buttery smooth. You can flip it open one-handed. Imagine a Hummer doing Tai-Chi! This tool is a "machine" in my opinion. It has gears, it has a precision build to it you have to feel to appreciate. I had already preordered a wood saw to replace the V-cut tool it comes with as this would be more useful to me. (I put the V-cut tool on my key ring to have as an emergency seat-belt cutter where I could actually get to it) Yes, the other tools take a little effort to pull out, but are hardly a reason to pass on such a great product. If you don't care about the assisted blades a regular Power lock will give you a few more tools and options, better yet get them both! August 2012 update: Still going strong! I've been using this five days a week since Nov 2010. Being in maintenance I use this at least four times a day. Nothing has broken on me yet. The power-assist blades still pop out like on the first day of use. I've read quite a few negative reviews about pliers breaking and philips heads snapping. Perhaps SOG got a bad batch of steel, I don't know. Mine has performed flawlessly day in and out. I don't baby it, and actually take pride in the little scratches and wear it gets. The black oxide coating has held up beautifully. It's almost like it's actually black steel, and not a coating. It has worn off a little on the rounded rivets and some edges, more character! I was looking for a lighter weight multi-tool for non-work EDC, and was leaning toward the Leatherman REBAR. They make great products, but for FIVE dollars more I ordered another Powerassist satin finish, a gorgeous looking tool. When you've used the smooth opening pliers, it's hard to go back to the traditional clunky opening ones. Even the extra weight doesn't bother me, it's actually comforting, feeling it on your belt. No other multi-tool is truly as one-handed as this with regards to the pliers and blades, and in an emergency when you may only have one hand I don't trust anything else. One last thing, Leatherman offers a 25 year warranty, SOG tools have a LIFETIME warranty, and if you break the implements you can ORDER new ones and install them yourself! A no-brainer guys (and gals). October 2013 update: Added the 1/4" driver a while back and bought the bit kit from SOG. now I can use any 1/4" bits. Still can't seem to break this thing. Don't baby it at all.

Here's the short version of what's below: 1) Very tough, excellent quality tool. 2) SOG as a manufacturer, and their LIFETIME WARRANTY are among the best in the industry (according to MY experience) 3) So buy it with confidence. Beat it up. SOG will stand behind their products! 4) The all black coating is kinda bad ass so extra cool points. Ok if you're still reading... here's my review: Let me start by saying this: I own a number of multi tools: a Leatherman Wave, Wingman, Rev, and Skeletool. I also own a Gerber MP600, Dime, and Suspension. And they're ALL great tools, so you won't be getting any comparisons from me. But I have a fair bit of experience with using all these tools over the years. So I purchased this SOG Power Assist multi tool right here on Amazon back in 2012. I wish I had taken pics of it and how I've used it over the years, because I've put it thru the grinder! It's been used well. Not abused, but used to it's full potential since I've owned it. I used it to build a dog run and I've cut tie wire to build a fence with it. I've used the end of it to beat down the lid on a paint can. Actually multiple paint and stain cans as I've used it while painting at work, at home, and any number of "Honey Do" projects for my wife. I've used it to repair a leak on my radiator, wire electrical outlets, and cable TV. It's repaired and tuned up my lawn mower, line trimmer, and leaf blower. It's on my belt every time I do yard work, and for every single home project I've worked on since buying it. It's been really good to me, and I've had nothing but good experience with this tool. Fast forward to August 2019. Now here's where things change a little bit. For the worse and then...for the better. I started to notice that the blade assisted opening wasn't working as well anymore. After seven years of serious service I wasn't surprised. To make matters worse, the blade also would no longer lock while in the open position OR when it was closed. That can be dangerous, so I ended up just leaving this multitool in it's sheath on my dresser, and pulled out my Leatherman Wave and just started using that one. (Great tool as well btw!) BUT, I really missed the SOG power assist pliers and wire cutters because of that cam/compound thing... They are SO good! Cuts wire like butter! So... I started shopping for a new SOG power assist multi tool, and since it's been 7 years I thought I'd look at SOG's website for a newer model. What I found was SOG's LIFETIME Warranty. It was such a simple warranty process! I printed a PDF form from their website, filled it out, then packed the form and my SOG into a small Priority Mail box...and a week later I got a brand new Power Assist multi tool!!!! I was hopeful they'd at least repair it, and they exceeded my expectations! Not only is this a great tool... But I can attest to SOG standing behind their warranty!

I have been wanting this tool for about a year or so and have only just now gotten one. That being said, my background is in Tactical Tools and Weapons, so there are certain qualities that I look for in a tool. I will attempt to answer the two most important questions in this review... 1- Does it do what I think it should? 2- Is it a good buy? The SOG B66-N has been long awaited. When I received it I was happy with the weight and feel. It's packaging was plain and simple (a Plus in my book) and it operated surprisingly smooth. The case is double-stitched black nylon webbing with a velcro closure. I was able to manipulate ALL of the tools one-handed. I did not like how complicated it was initially to open the two PowerAssist Blades (Plain grind and serrated). There is a small slide lock that prevents the blades from coming open when you don't want them to which is more tricky than I thought it would be (It has a mind of it's own and likes to lock itself indiscriminately). The second thing that I did not like was the small circular studs that must be pushed up to unlock the open blade and allow it to close, are very small and have 90 degree edges, so they are not comfortable to operate. The good news is that unlike many knives and multi-tools I have purchased in the past, the secondary tools stay where they're supposed to when they are supposed to, but are very easy to open and close one at a time. The "Compound Leverage" Pliers are The Heat, and they function very well. Overall, this knife does do what I think it should for my uses, and once you understand how it operates, is is not at all difficult to use. The B66-N is a good buy for my purposes (Law Enforcement). I have read a review on here about the spring assist function failing and the screwdriver tool snapping off, but nothing is perfect and those reviews do not address the manner in which these tools failed (Were they torture-testing their tools?). More importantly, SOG advertises a LIFETIME WARRANTY on this item. While it would be a hassle to send it back and await a new tool, SOG does indicate that they stand behind their product for a LIFETIME of usage which is better than most other companies that I have had experience with. Also, according to SOG's website, the founders are Military Men, which means they know what tough tools are made of. All things considered, I think this tool is a great buy. I consider the price I paid ($71.00) to be a fair price for what you get. The LIFETIME WARRANTY is a reassuring feature if you have not had any experience with SOG in the past (This is my first). Although there are some downsides to the knife, It is still an excellent tool that is deserving of a good review. Also, check out the following YouTube review on the B61(?) by "Nutnfancy". It is a review of a different knife, but it is very similar to the B66-N and very applicable... [...]

I bought this pocket tool almost 10 years ago and it’s still holding up amazingly. First how I have used this: I was a corporate trainer for a large restaurant company, and I would travel to open brand new restaurants (with lots of new equipment and problems). This was my every tool (including being used as a doorstop to hold open countless walk-in coolers). I’m also a sport angler, and I use this as my hip pliers (removing hooks regularly and leaving up the cord cutter for cutting fishing line, both mono and braided).In addition, I do work on small two-stroke engines, and many times have reached for this tool rather than my other sets of pliers. And finally, I recently constructed a Tiny Home from the floor up with my trusty SOG at my side. My particular tool has been used and abused!! Other than regular cleaning, tightening (which is made easy to do for the blades, player heads and all flip out accessories) and the occasional sharpening I’ve had to do nothing to maintain this tool. The knives both spring quickly out and keep tight for a good amount of time. The biggest selling point for this tool for me was the ability to open the knife with one hand. Works perfectly for this. I love the pliers because they very slightly taper down right at the end, leaving them strong but also petite enough to fit into a lot of hard places (was very helpful when doing small engine work). They are stronger than expected, and the wire cutters have just begun to dull and chip (you can see from the pictures the condition after 10 years) For fishing, I found that locking the cord cutter in the up position and putting it back in the holster kept it safely out of the way but easily accessible when changing lures often for that selective fish. The black oxide coating has held up very well, along with the genera construction of the tool (and I have for sure treated it roughly over the years). My only complaint is the safety lock for the spring loaded knives is loose and regularly slips to the “on” positions. Meaning when I remove it with one hand and flick open the knife I must pause, turn off the safety, and then flick open again. Annoying and time consuming, but still doable with one hand and only happens every so often. In conclusion, this is easily the best tool investment I’ve made in my life. I have used this tool in more applications, for more years, and with less maintenance or problems than any tool or spent money on. Get this tool if you don’t want 100 useless accessories but need an quick access blade and durable, versatile set of pliers. I find myself making a review because it’s finally time for another set (only because I am gifting my old pair to the GF, who has taken up fishing) PROS: Durable Easy access knives Strong and versatile pliers Good accessories, no extra fluff CONS: Safety for knives

I purchased this product when the blade on my 6-year-old leatherman kick snapped in half. After some intense research, I had narrowed my choices down to two products, Gerber Flik-MultiPlier, and the SOG Power Assist Black Oxide. Conveniently, two of my friends happened to own these very tools. I was intrigued by the Gerber's sliding-pliers design, and it was originally my first choice. However, after being given free reign over the tool for a day, I found that the feature was more of a boon than a benefit. The mechanism lacked intuitive operation, and significantly decreased the handle-throw of the pliers. The outboard tools were nice, but often ended up flipping out via their own means, as the tool cover was not particularly good at its job. The Gerber, as I see it, was an attempt at innovation, but fell slightly short of the mark. When I was given the SOG to use for a day, the first thing I noticed was the weight. It is significantly heavier than the Gerber, and (at least to me) this was a sign of much higher durability and build quality. The pliers moved very smoothly, and had more throw than I had ever seen, made possible by the geared movement. The tool cover latched into place securely, and the tools are located on the inside, adding an extra degree of security. After admiring all the utility-bits, I moved on to the flagship feature of the product, the blades. The spring assist mechanism is extremely reliable (I have never had a single failed deployment), and is highly addicting. The blades move out just as quickly as on a spring assist pocket-knife, and are unnervingly sharp out of the box. The locking mechanism is solid, if not excessive, and is very easy to reset. In all, this is probably the best multi tool I have used, and owned, to date. SOG may not be well known, but I truly feel sorry for their lack of recognition, as they have created a work of engineering brilliance.

I purchased this multi tool April of 2017, it broke on me today (March 2026). I have carried this absolute beast in my pocket for 9 years, I have physically abused it daily (steel industry), used it as a hammer, prybar, and whatever other ungodly things I could put it though. the amount of times this tool has came in handy, uncountable. yes it broke, but I couldn't have asked for a better lifespan than 9 years.

I purchased this a a gift for my father and I own the same tool in the plain stainless steel finish. It's a great multi-tool. Super durable and just plain beefy. If you're looking for a light little pocket knife/tool this probably isn't it. Maybe a Leatherman Squirt or even a SOG Paratool. The black finish is actually a lot nicer than the stainless steel because it doesn't show fingerprints as badly. I have found that this tool has replaced my daily carry pocket knife (a SOG Flash II) for a couple of reasons. First, the pair of assisted blades. Having a quick choice between the straight or serrated blades rather than having both in one blade is nice. The other thing is that carrying a multi-tool rather than a dedicated pocket knife tends to be less intimidating to people in the general public. When I pull out the Flash II people's eyes tend to widen a little and they make snarky comments. The PowerAssist blends right in as just another tool for most people and the only raised eyes and comments have been from folks admiring the thing. The fold-out tools are of the same super high quality and the locking mechanism works well. I also appreciate the V-Cutter for cutting paracord, straps, etc. I wish there was a more elegant way to operate the little cover that goes over the tools, but it serves it's purpose well in allowing a very comfortable grip on the pliers. This thing makes an awesome gift. My father received his and called me within minutes of opening to talk about how nice it was and how he'd probably never need another multi-tool again. It will definitely be appreciated by those who are handy, or who work on machines for a living. Although, one of the things my dad mentioned was that he wasn't sure when he would ever need the blasting cap crimper, but hey, ya can't win 'em all. :) Great tool, 5 stars, you will not be sorry that you purchased this tool and the price on Amazon pretty much cannot be beat.

Finalmente posso fare, dopo un po’ di esperimenti, una recensione a questo bellissimo prodotto. Il SOG PowerAssist si presenta abbastanza robusto e funzionale. Ovviamente non abbiamo fra le mani un lama fissa e questo dobbiamo sempre ricordarlo. Si tratta di un multiuso è da tale va adoperato. Innanzi tutto partiamo dalla funzione principale: la pinza. L’apertura è estremamente morbida, anche grazie a sistema a ingranaggi SOG che permette tra l’altro di imprimere maggiore forza di leva nell’utilizzo. Abbiamo poi, su un lato, due coltelli di cui uno a lama liscia e una lievemente seghettata. La particolarità di queste è l’apertura assistita. Basta fare pressione sul gancio d’apertura e la lama farà il resto. Dall’altra parte sono presenti vari utensili quali: • cacciavite a stella • molteplici cacciaviti a taglio • apriscatole (due tipi) • Lima da ferro • taglia cinture\corde: che taglia veramente di tutto. Conclusioni: veramente un bell’attrezzo, utile e (a mio parere) indispensabile in molte situazioni. Come detto all’inizio bisogna sempre ricordarsi che non abbiamo un coltello a lama fissa, oppure una pinza da meccanico, quindi non è a usarsi per prestazioni estreme.

I had lost of different multi-tool in the army but this one is the best I had so far. Rugged, solid and the pliers are very strong, able to cut to wire fence with no problem, I guess you get what you pay for. The locking mechanism on the blades and tools takes a bit of getting to but very useful.

Bin vom dem SOG Werkzeug begeistert. Habe es schon des öfteren Benutzt. Was besonders gut ist, die Messer sind mit einer Sicherung versehen, so das ein unbeabsichtiges öffen verhindert wird. Auch die Lieferung war sehr zügig.

Tardó casi 3 semanas en llegar. En vez del modelo óxido negro, me trajeron la satin, y encima, de powerassist nada de nada. La hoja de filo recto, va durísima y la serrada, a veces funciona y a veces le pega por bloquearse.

Después de haber experimentado por tanto tiempo el trabajar con herramienta multiusos Victorinox. Quiero comentar que me se me hizo muy solida para el trabajo, el cual tiene que ver con el mantenimiento de equipos de computo, me fue muy practica para pelar cable, las navajas tienen un excelente filo además que el sistema de bloqueo me parece solido y seguro. En realidad se me hizo un buen producto y su precio es muy adecuado.
