Some of you may have read my post in the "Gunter" thread where I commented on the need to keep the pivot tension snug. Well, this applies to all knives with an adjustable pivot screw, and I do, indeed, keep mine so on any carry knife. Last night, I went to take my Salsa out of my pocket to put it away for the night and found that the blade had started to open in my pocket. Now remember, the Salsa carries Tip Up, not my preferred mode, but I like it anyway. I was very fortunate in not cutting myself or my pants and was able to extract the knife and I still cannot figure what happened to start the blade opening, especially given the distinct detentes holding it closed that Spyderco builds into the model. I have adjusted the pivot tension very tight and I am now considering dropping the knife from my work daily carry mode as I can not afford to have this happen again. And that is why I distinctly prefer Tip Down carry.
