The wisk & pick is used to maintain your musket to clean the pan and clean out the touch hole. This wisk & pick and chain is made of solid brass . To be completely honest we have not seen a brass brush in any museums, we have seen horse hair brushes. The hook at the top of the chain is designed to go around a button on your coat, or can be sewn to your coat ,cartridge box strap or your hunting bag. That way your wisk & pick is ready to use. These are hand made including the chain.
