Flex Coat Bone Burnishing Thread Tool
For many years here at Flex Coat we have used a tool made from a polished cow bone for burnishing and packing thread. This material seems to be the perfect hardness for working your wrap without damaging the thread or blank. Ergonomically shaped, this 5 inch tool fits comfortably in your hand. A really nice thread tool.
