Rated 5 out of 5 by from this auto is awesome I got mine about 6months ago, now I'm not sure I should admit to using this as a do all tool but I do. It's a great tool,it holds a great edge. My only concern is I hope the spring holds up.

Rated 5 out of 5 by from Best knife I own I bought it a few months back and use the heck out of it. Holds an edge better than any of my other knives and it's built like a brick shot house. Will carry this until I break it or loose it then I'll buy another one!

Rated 5 out of 5 by from Best everyday knife I've ever owned! I bought my knife about 6 years ago,maybe more,and it's been the best "everyday" knife I've ever owned. I always have it in my front pocket,it's the first thing I grab every morning,even before my wallet!! I've had it hunting,fishing,boating,camping and with me even while I work,I'm mechanic and I'm constantly rolling around under tractor trailers on concrete floors 10 hours a day,and have never had an issue with my SOG. I'd be lost without it!!.... It's been through H$L& and back,replaced the pocket clip once and the spring once in al these years,it has scars and marks on it,but just as good as the day I got it!!

Rated 5 out of 5 by from Awesom Knif I have had this knife for a while now and it has never let me down. Holds an edge even after cutting heavy climbing rope during weeks of field activity.

Rated 4 out of 5 by from Good to go!! I bought my knife about two months ago. This knife has always met my need on demand. It's ability to be open at a moments notice to accomplish the required task gives me that feeling of dependability and faith, without that reliability of any piece of my gear I wouldn't take it. I trust my gear like I trust the guy to my right and to my left, zero room for failure when the need arises. Very pleased and highly recommended!!!

Rated 5 out of 5 by from Best knife I've ever owned My wife bought this knife for me as a gift somewhere around three years ago. I had several other brand name autos which now ride in a drawer or the truck. This is my favorite every day carry knife. Twice I have broken the clip and customer service sent new ones quickly. Razor sharp out of the box and holds a great edge. The auto opening mechanism and locking mechanism function flawlessly. I'm as proud today as I was the day I got it. Thank you for a great quality product SOG.

Rated 5 out of 5 by from fantastic Knife Fantastic knife, feels good in the hand. It holds it's edge and doesn't need a touch-up very often. I have opened and closed it hundreds of times without any problems and it is a beautiful knife to look at.

    Pocket clips can be broken if they are accidentally caught on foreign objects while wearing. To help prevent such occurrences, SOG recommends that you wear your knife in your front pocket, with the knife inside your pocket. If, for whatever reason, your clip bends or breaks and you would like to receive a replacement, fill out the Clip Request Form, or email/call SOG's warranty department. Damage to a knife handle because a clip has snagged is not considered "normal," and any such damage will be assessed under warranty. Learn more about replacing pocket clips in Knife & Tool Care.
