How do 3K, 12K, and raw unidirectional carbon fiber compare in paddle construction?

The 'K' in carbon fiber denotes the number of carbon filaments per tow (3K = 3,000 filaments; 12K = 12,000). 3K cross-woven carbon creates a tight grid that resists torsional twist while offering crisp ball feedback. Raw unidirectional carbon layers provide extreme longitudinal stiffness for powerful baseline drives. Top tournament paddles frequently blend a raw Toray T700 outer face with multi-axial carbon sub-layers.
