You guys all assume that was loktite. Could have been a misaligned screw. Generally, Spyderco liners are harder than their clip screws, and it's possible to misalign a screw, ruin it or and get it stuck. The screws are so soft that it's annoying sometimes, in particular on Spydercos from Taiwan. That's why I always start counterclockwise until I hear a click, then screw the screw in clock-wise. Anyways, John, sent you a PM. Roland.
