At Firestone, the most profound details are carved by hand. We partner exclusively with Marlen Hazel, a master hand engraver based in San Francisco who has practiced traditional techniques since 2013, using analog gravers and the steady strength of her hands. It is a rare, deliberate method in an era of automated and pneumatic engraving, giving every inscription the weight of a true heirloom.
