Sorry if this has has already been done to death but I’ve just got a new Spyderco Manix 2 XL (CPM S30V) and the lock release is ridiculously stiff like I have to use two hands. I’ve tried all the things that Spyderco recommend, leaving it half open for a few days etc etc and it’s still way too stiff so can anyone suggest anything perhaps a bit more drastic as I want to keep the knife but no way can I operate the button safely ? Thanks.
