I just received the Ayoob today what a pleasant suprise waiting for you when you get home from work. The knife is in my opinion is perfectly designed for a defence forder with either grip position the knife lines up symmetrically in your hand. The lockup is rocksolid, wonderfully put together, overall a aesthetically pleasing knife. I have one question can you adjust the blade tension on this model and if you can how much of a turn should you go from the tight position?
