Be careful pulling the knife from your pocket while sitting down that you don't cut yourself, or your pocket. I don't know why, but I had the worst luck with them. The first one I ordered from a local dealer and the liner lock would barely engage the tang. Even after adjusting the pivot screw, the lock would not engage properly. I returned it and received another as an exchange. This one locked up okay, but after one week of playing around with the "wave" feature, the liner lock bar worked it's way across the tang almost making contact with the washer on the other side. I could not believe that a titanium liner lock would wear out that fast. I adjusted it by tightening the pivot screw but the lock bar still engaged more than halfway across the blade tang and I had to deal with stiff action. A buddy of mine offered to buy it from me and see if he could tinker with it , so rather than sending it Emerson Knives, I sold it. My third one, I bought at a retailer after examining several samples at the store and it was acceptable. This one I ended up trading for a Microtech.
