CUSTOM SHAPED BLANK

摘要

A blank may include a tang section, a base section, and an angled section with a recess. The tang section may have an outer surface with an outer diameter. The base section may have an outer surface with a diameter greater than the outer diameter of the tang section. The angled section may lie between the tang section and the base section and may have an outer surface that transitions in diameter from the outer diameter of the tang section to the outer diameter of the base section. The recess in the angled section may be shaped to engage a tip of a former.
