Pedersoli rock stone 7/8" 5 pcs is a set of flints that initiate the ignition of gunpowder in a rock weapon.
The ignition of gunpowder on the pan of a rock weapon occurs from sparks, which are created when the stone (mounted at the cock) strikes a metal scraper protruding from the side of the breech.
The set includes 5 stones of about 16 mm in size.
