AQE-2W9Flint

Brandon, Forest Heath, Suffolk, England, UK

Field of View: 90 mm

Hand-knapped flints for use in flintlock firearms from Brandon, Suffolk. Each flint measures 24x17x8mm and has a sharp, chisel point where it is designed to strike the steel (frizzen). These examples were knapped in the last two decades by Tom Fuller of Brandon, who knapped gunflints mainly for the world-wide historical reenactment market, and those who shoot original or reproduction flintlock firearms for sport. Hand-knapped Brandon flints are considered some of the world's best for this purpose. These examples were purchased in the US.
