In calligraphy, which tool is typically used to create Celtic letter styles?

Celtic letter styles are traditionally characterized by their intricate designs and elaborate embellishments. The use of a calligraphy nib is particularly suited for creating these styles due to its ability to produce varying line widths and sharp angles, which are essential features in Celtic calligraphy.

A calligraphy nib, often fitted into a holder, allows for a controlled flow of ink, enabling the calligrapher to execute elegant strokes with precision. The flexibility of the nib can create thick and thin lines, adding depth and texture that are hallmark traits of the Celtic aesthetic. This versatility also aids in achieving the decorative flourishes and knot work that define Celtic lettering.

The other tools listed do not typically provide the same level of control or the distinct line quality important for Celtic styles. For instance, brush pens offer a different aesthetic more aligned with brush lettering rather than the distinct, sharp features of Celtic designs. Fineliners and gel pens, while capable of producing fine details, often lack the flexibility needed for creating the dynamic strokes associated with traditional calligraphy.
