I have both second and third generation mx18. The one with Hinderer's name on the blade (which is the second generation I think) the blade is closer to the G10 side of the handle when closed. There is more space on the titanium side of the handle. It's not scratching the handle but not perfectly centered like the third generation model. I tried loosenig the pivot and it touched the handle. By tightening the pivot the blade goes alittle to the titanium side but still closer to the G10 side. Anybody there who has both second and third generation model and compared them? How is your second ones centered? Can you think of why this is happening? I wanted to post pictures but I'm sorry I did not pay the forums to let me do that.
