This is a tying tool for fly fishing that I purchased previously. It's used to apply instant glue to materials by putting the glue on the tip of the needle. It's a tool for applying a tiny amount of instant glue to a specific point on the material. Also, since the glue quickly hardens on the needle, you put the needle into a dedicated container and scrape off the excess glue on the metal mesh inside. This allows you to use the needle in a fresh, clean state every time. Please understand that this is a used item before bidding. Also, as shown in the image, the needle tip is slightly bent. Total length: 100mm Base diameter: 33mm Handle diameter: 6.6mm
