I just bought an Emerson cqc-7, its my 1st Emerson and I see why a lot of people have good things to say about these knives. It seems like a very good knives so far and I like it a lot. My one problem with it though is that the liner lock seems to get stuck when I open the knife and its very difficult to disengage. If I open the knife very fast or use the wave to open my knife I have to use something like a screwdriver to pry it to disengage it. I have heard that some emersons need a brake in period but this does not seem normal. Is the lock supposed to be like this? If not what should I do? I tried oiling it and that did nothing.
