I was about to post this. It's very easy to apply enough pressure to the outside of the lockbar that it's forced inward and doesn't allow the detent ball to move out of the detent. Glad you figured it out!Phat B wrote:Gah I just figured it out. Being my first framelock, I was completely unaware that I was pressing my middle finger against the framelock when opening, thereby adding pressure to the process and making it difficult to open. Much smoother now. Now I just gotta find a place to put that finger when I open it.
