There are 6 KATA BLADES, 2 TYPES of engraving on each, BOLD & ART.
BOLD is softer, elegant, brighter, has excellent gradation with beautiful highlights. ART is darker, chaotic, surprising and texturally more aggressive.
Designed with freestyle light painting in mind; these kata blades will influence your movements based on weight distribution so they will move differently in hand.
