What would be the proper tool to access the ring in the AR's handle. It looks like it would have to be some kinda fork like flat head screw driver. If anyone knows what kinda tool is used to losen and tighten this up I'd like to know it's name and where I can find one. I know the other side uses an allen head. Thanks guys. And also if I take my Strider Folder apart from time to time to clean it is there gonna be any kinda springs or anything that are gonna jump out at me. Should I make a map when taking it apart? Or is it pretty straight forward?
