Kid -- The best way is to use the tool, and even then I can't always get them out without damaging them. Without the tool, you'll need some type of thin, flexible material (metal or hard plastic) to slip in between the hole and the grip, then rotate around to separate the two. I doubt that a screwdriver or knife will work. Maybe something like a sparkplug feeler gage, but the thin ones are sharp so don't cut your hand. -- JohnP
