Picked one up a couple of weeks ago. Its been in my pocket ever since then. The action was a little tight when I first opened it. I dialed it in and lubed it, now it snaps open with authority. That raised another problem, the slippery handle. I ordered some guntape, and cut a couple of small pieces (think pinky fingerprint size), and applied them where your thumb and middle finger go when flipping open. It works perfectly IMO. The end of the handle doesn't try to come away from my palm at all anymore when the blade snaps open. Its doesn't drag when pulling it out of the pocket, and added just enough traction to make it feel secure in the hand. I only hope that it will stay where I put it. The reviews are positive though, lots of people with the stuff on their guns and it hasn't moved. I wish I could upload a photo. I do love the knife, very slicy, comfortable in the pocket and hand, not too heavy, and it has a machine like "shhick" sound when opened. It works great for all light to medium duty cutting. I wouldn't use it on anything too hard for fear of chipping the s90v on a very thin edge. I know this is an old post, but that's my two cents.
