frizel

plural frizels

1. historicalengineeringA movable furrowed piece of steel struck by the flint, to throw sparks into the pan, in an early form of flintlock.

   To this succeeded the Snaplance ^([sic]), in which a motion was given to the dog, or cock, and a movable plate of steel, called the frizel, or hammer, was placed vertically above the pan to receive the action of the flint.
