When you have powder residue to build up on your frizzen and pan this is a very handy item to have. The broad brush is for use to clean the frizzen while the narrow stubby part is used to clean out the pan. A fouled frizzen will not spark or spark improperly and a fouled pan will have a tendency to clog the vent. This flint whisk is of the highest quality and workmanship. Hard bristle brushes set in a well executed and turned piece of mahogany. This will make an excellent accessory for your cased set of flint dueling pistols. Made in England.
