I'm always searching for the perfect tool to help with some aspect of the craft. I'll spend hours making a jig or some specific tool to fill a need. Then find a better one on Amazon. I've been fighting finding something perfect for detail sanding in small crevices when I safety clearance a Macro grip. I've tried a number of things like wrapping sand paper over a jewelers file. I figured I'd start a thread of helpful tools and invite others to do the same on this thread.
