I have made about 4 of the Blade Kit Click pens. I like the way they look but the click mechanisms keeps sticking. Sometimes it won't click to extend the tip of the pen. If I completely unscrew the mechanism and screw it back on, it works fine. This is my first time using a kit with the Schmidt click mechanism and I am confused because I have only heard good things about them on this site. Does anyone have any ideas about what id happening?
