I have had several people ask about this great little tool for fly tying. Essentially it creates a red hot tip that burns or melts anything it touches. I use it to clean up unruly deer hair, thread, etc especially near the eye of hook! It certainly helps to clean up the head of your flies. I started to use this tool when tying flexo crabs. They look a lot better once all the rough edges are cleaned up!
