Steel nibs demand exacting tolerances when you're working at extra-fine scales. Hunt crafts these Globe 513EF nibs from premium steel in their USA facility, hand-finishing each bowl-pointed tip to maintain consistent line width through detailed industrial lettering and technical drawing. The extra-fine designation means genuine precision, not marketing speak, for work where character spacing and stroke uniformity matter.

Bowl-pointed geometry distributes ink evenly across the tip, preventing the catches and skips that plague cheaper nibs during rapid lettering sequences. This design originated in industrial drafting rooms where legibility at small scales was non-negotiable, and that heritage shows in how the nib performs through extended use. The steel holds its edge and flex characteristics session after session.

These nibs fit standard pen holders, Speedball's #9451, General's Cork Grip, or Speedball Classic models all work. You'll need to purchase a holder separately, which lets you build a collection of nib styles that share common handles. Serious letterers keep multiple 513EF nibs on hand since they're affordable enough to replace when dulled rather than struggling through subpar performance.
