Ha Ha, funny stuff there. Seriously this is a folder, right? spray the hinge area with Kroil, WD-40, or other PENETRATING oil. Scrub the hinge area with a toothbrush and spray until the oil looks clean, work the hinge back and forth many times and the oil will turn gray or red depending on the metals involved. Spray again, work hinge, spray, etc. Eventually the oil will be less gray or red, when it stays clear the hinge is good. As far as the blade goes, Most any good oil, 0000 steel wool and elbow grease will take care of that. If you want to Polish the steel use flitz, brasso, etc. The oils/polishes really dont matter that much unless you got some exotic steel, the important thing is elbow grease. Do not use sandpaper! lol, I've seen it tried.
