Cons: Ease of Opening, Lock Ease of Use, Lock Type
Lightweight money clip
Great blade. Body is quite narrow so blade movement in and out is not as smooth as some knives. I use it as a Money clip because I really like the knife, but if I pull it out of my pocket and the pocket clip is under the cash, it is very obviously a knife. If I'm going somewhere that possibly showing a knife makes me uncomfortable I switch back to a money clip.

The Lightest and Most Comfortable EDC
This is the lightest pocket knife I've ever owned,and it's so thin you barely notice it when it's clipped inside your pocket. Yet, it's as sharp a knife as you could ask for, and it is the easiest folder to open and close. Just point the knife downwards and open the lock---the blade falls out of handle with just gravity or maybe a gentle wave of your hand. Releasing the lock helps snap it open. You can close it by pointing the folder tip up and opening the lock. How easy, fun, and convenient is that? The blade has a little lateral wiggle when open---not much more than other folders I owned, but this isn't one of high precision folders that has no play in it at all. Still, the carbon slabs should be strong and tough enough for the knife to last a long time, and SOG guaranties it for life. The handle's too thin for sustained, heavy cutting chores, but it's fine for typical urban tasks like packaging, cardboard, and food. I'd prefer a narrower blade shape but the blade's width makes it useful for things like spreading cream cheese. I didn't think I'd like this knife as much as I do, but now it's the folder I carry almost every day, Spring tension on the pocket clip is just right. It's so light and comfortable I don't notice it, but it's easy to pull from my pocket and open when I need it.
