I just received my Siren in the mail and LOVE everything about the knife. The ergonomics and design are exactly what I was hoping for when my son pre-ordered it for me. Unfortunately, after opening it up 15-20 times the blade has begun binding after it opens about 45 degrees. By the time it is 90 degrees open I really have to fight the binding to open it the rest of the way, like to the point I feel safer opening it with two hands instead of my thumb in the Spydie hole. It binds while trying to shut the blade as well. This is a real bummer at best, especially after waiting so long to get the knife. I called Spyderco and the best they could do was to tell me to send it back under warranty. Before I do that, can anybody tell me if this is something common to Spyderco's G10 knives and if there might be a common fix such as oiling the blade pivot, loosening the pivot screw or anything else I might not know about. To date, I only have a Salt FRN and a Delica FRN. They slicked up with use. I thank you for any suggestions that might help me not have to send the knife back to Golden for warranty work. Edit: If I hold the lock bar TOTALLY depressed there is no binding of the blade at the pivot upon opening or closing. If I let up any pressure at all on the lock bar the binding is there again. Appears as though there is excessive contact being made between the lock bar end and the back of the blade (not the right technical information, I know).
