The Definition of Damascus Barrels
Barrel tubes built up by twisting alternate strips of iron and steel around a fixed rod (mandrel) and forge-welding them together in varying combinations
according to the intended quality and the skill of the maker. The rod was withdrawn, the interior reamed and the exterior filed until the finished tube was achieved.
Damascus barrels may be recognized by any of a variety of twist or spiral patterns visible in the surface of the steel.
Before the 20th century, barrels were typically built in this manner because gunmakers did not have the technology to drill
a deep hole the full length of a bar of steel without coming out the side.
