6mm (wide) comfort fit grooved Damascus Steel men's ring with an acid finish. Damascus Steel is a unique blend of two different types of steel forged together to make a beautiful, durable band. An artisan blacksmith first layers two types of steel that are then fused at a high temperature. Mechanical hammers weighing 600 to 1000 pounds are then used along with other heavy equipment to form patterns of different types. Our Damascus Steel men's rings are then cut from a solid block of this patterned steel. While basic pattern types can be repeated, no two rings will ever be the same.
