Congrats. I EDC my 561. Have been every day since it first arrived earlier in the year. It was a bugger to open and close when I first got it which concerned me a bit. I turned to the forums which suggested that I just continuously open and close it to break it in. Also, to assist with the initial sticky lock I rubbed the lock face with a graphite pencil which loosened things up nicely. I'm not sure if you'll encounter the initial super strong detent or sticky lock like I did but if so, have no fear. My 561 now flies open with so little as a nudge from my index finger on the flipper. It also opens just as easily with a flick on the thumb stud. I consider it to be my favorite folder in the stable. I hope that you enjoy yours as much as I enjoy mine! Use the heck out of it.
