Hi all! I was fooling around with a mic (a shure SM 58) and recorded myself opening and closing a zippo lighter. Well, one of the clicky sounds that I recorded sounded nice enough to me for a sound of opening the main menu while in game or the like. Anyway, do whatever you wish with it, here it is in flac format.
It is a very nice click sound and I should know, I have heard more than one!

I took "do whatever you wish with it" to heart and uploaded it to opengameart under cc0/public domain:
