The handle was designed using simple geometric forms, carefully composed according to the principles of Crdobas Proportion, a system rooted in the architectural tradition of Crdoba and mathematically comparable to the golden ratio. This proportion is defined by the relationship between the radius of a circumscribed circle and the side of a regular octagon, a geometric logic that played a fundamental role in Caliphal architecture, with roots in earlier Roman aesthetics, and has been present in arts and buildings from ancient times to contemporary constructions. Guided by this harmony, the design achieves a balanced and refined form. Its name and color draw inspiration from the sky over the city and the distinctive blues found in Crdobas patios, creating a subtle connection to its origin.
