The Roughneck get its name because of its durability. If you want a ring you can wear and beat the hell out of, this is the one for you. It is hand machined out of a special grade of titanium, that is strong but can be cut off in the case of an emergency. This design also incorporates a thin offset Antler inlay leaving more surface area of titanium than inlay that can be destroyed in the Roughneck environment. Millimeter width varies depending on size of ring. Can be made in sizes 6-15. If a bigger or smaller size is needed please call or text me. 541-414-7938 All sales final.
