Greg Porter, of Greg’s Garage, is a YouTube DIY mastermind that has tackled everything from homemade guitars and CNC machines to vintage tool restorations and custom paint jobs. He got fed up with his Sharpies always rolling around the bench so he set out to create something better: the Twisted Sharpie. Each is handmade in the U.S.A. out of a piece of twisted steel that’s been built and finished to last far longer than the permanent marker cartridge inside of it. When that happens, pull out the cartridge and install a new one to keep working. Each pen is serialed and comes with a card numbered and signed by the designer.
