    Tested at over 1000 lbs. of force (measured at the lock), far surpassing conventional lock strength.

    Lightning-quick, one-handed opening and closing capability.

Customer Ratings & Reviews

Pentagon Elite I - Clam pack is rated 4.9167 out of 5 by 12.
Rated 4 out of 5 by from Very utilitarian I have had this nice for several years and it is always read when need . The blade holds a edge great.

Rated 5 out of 5 by from Simple, Efficient, Effective. I purchased my SOG Pentagon Elite I at the suggestion of a friend who carried the slightly larger Pentagon Elite II. I found the SOG PE I to be everything I ever wanted in a knife and more. Whenever I needed my knife, I could draw, cut, close, and return to my pocket in a smooth and almost automatic motion with one hand. The blade opens in a breeze and after pressing down the lock, closes with the same fluidity. Simple, efficient, and effective.

Rated 5 out of 5 by from The best everyday carry knife you'll ever need! This is the best personal protection everyday carry knife you will ever need.

Rated 5 out of 5 by from Trusted and reliable I have owned this knife for several years and it has become as essential to me as my wallet or car keys. I wont leave my house without it. The knife is small enough to fit comfortably in my pocket, and sturdy enough to endure the rigors of militar work.

Rated 5 out of 5 by from Slim! - Swift! - Sharp! I've had my Pentagon Elite for nearly 10 years and it is still one of my favorite everyday carry knives. It is slim and fits well when clipped onto my pocket. The retaining clip and cross hatched handle easily keeps it in my hand. The arc release/lock button makes deployment fast! It also maintains a very sharp edge. I've recommend this knife an number of times over the years and will continue to recommend it. I hate buyers remorse and therefore strive to buy quality products that will endure long after the "deal of the day" is gone. Great quality, great value!

Rated 5 out of 5 by from Tremendous value I have not owned a lot of SOG knives over the years but the ones I have owned (Pentagon fixed, NW Ranger, Tomcat III) they have been excellent. I used to own the original Seki Pentagon fixed blade many years ago and while browsing on e-Bay recently I came across this folder and saw that it too was a Seki made knife, featuring a good steel and SOGs great Arc lock. For around $100! I immediately thought: heck, why have I never had one of these? Well, to cut a long one short, I ordered one up and have been carrying it pretty much non-stop since I got it. Now I would like to add that I own over 30 knives, including customs and many high end productions and the Pentagon Elite I stands up to any of them. This is mainly because of the use of VG-10, an excellent steel, and the Arc lock, which is a fantastic lock system, similar to Benchmade's Axis lock, which I like very much. The other feature I really like is the Shark Tip point, which is unique to SOG as far as I know. This tip just demolishes blister packs, which as we all know can be a bear to open if you dont have a sharp tip on your knife. They are also light, easy to deploy and carry and I particularly like the blasted finish on the blade and clip. It is really nicely done, not cheap and nasty like some bead blasted finishes. In fact, I like the Pentagon Elite I so much I have now ordered the Pentagon Elite II with the 5 inch blade. SOG has done a GREAT job on these folders and I hope they never change them (although a plain edge option on the Pentagon Elite would be great). They are tremendous value, so check one out, you won't be disappointed.

Rated 5 out of 5 by from Great Toy! I bought a Pentagon Elite II a couple of years ago but lost it during my last deployment. Now just bought this one a month ago and love it! Easy to operate, both open and close, especially with just one hand. And very easy to maintain.

Rated 5 out of 5 by from 7 years and still strong My wife bought this as a Christmas present and still is my EDC (Every Day Carry) knife, I own several other brands of knives , but this one is the one I depend on, some of my co-workers have used it and they have bought their own after trying it, SOG makes such great knives they keep the edge well and they are easy to open and close without any special automatic mechanisms, I 100% recommend this awesome knife.
