On a flintlock rifle or musket, when the trigger is pulled, the flint is scraped down a metal cover, showering sparks into the priming pan, firing the weapon. That metal cover is the frizen.
Rifle flints are just knapped pieces of flint that are sized to fit in the cock (hammer) of a flint lock rifle. They are sharp on the end that protrudes from the jaws of the cock. This is the piece that actually contacts the frizzen to scrape tiny curls of metal from the frizzen (causing sparks) to light the primer powder in the pan.
