So I own 15 PM 2's. All of which are new and unused except 1. Upon loosening the pivot screws on most when received for cleaning and lubing. At least one pivot screw is usually over tightened or to much thread locker. As long as I firmly hold the knife in one hand and securely place my Wiha torx and very firmly turn they always come loose. Well the last four i have done this with to were a real issue. I bared down and finally the screw released, well so I thought. It remained rather hard to turn the torx and upon looking closer. I could see the metal was soft and the torx pattern was now more round or ground out. I could tell it was softer metal than usually used. Has anyone else incurred this same issue? It was only pivot screws as stated earlier. I am sure hoping Spyderco well make good on this. If not it will be a real bear to get these out with out damaging the knife. I could have gone all day with out this happening for sure.
