I just love the efficiency of this knife that I bought two stainless models (gave the serrated one to my brother). During a gun show, could't help but fondle every rookie that's on display until I picked up a G-10 model and was really impressed by the lighter balanced feel but more importantly by the very solid lock-up.Of course I bought it, is there a choice? As soon as I got home I loosened the pivot screw to check for blade play. Other knives do not exhibit blade play when the pivot hardware is tight, but movement is evident if loosened. But not this particular rookie, still feels like a fixed blade. Hats off to the Spydesign and QA teams. BTW, also bought another engineering marvel,model 99 experimental. What a knife. Thank God the Del Mar gunshow is not every weekend,otherwise poor house here I come.
