DLC FIXED BLADE WITH BLACK TITANIUM-COATED MOVING BLADE (J01) — THE HARDEST BLADE SPECIFICATION IN THE CATALOGUE: Diamond-like carbon coating is a wear-resistance technology borrowed from cutting tools, not a marketing finish. For a salon-channel brand, blade longevity under daily commercial use is the entire purchasing argument.
EXTERNAL BRUSHLESS MOTOR WITH 3000mAh AND 180 MINUTES (J01): Three hours of continuous runtime is a full salon shift. Brushless construction removes the brush wear that ends the service life of conventional clippers under professional duty cycles.
A MATCHED CLIPPER-AND-TRIMMER PAIR WITH WIRELESS CHARGING BASES: J01 as the bulk-removal clipper, J02 as the 2500mAh / 150-minute detailing trimmer with ceramic moving blade. Barbers buy in pairs, and a brand that sells only one half of the pair loses the other half to a competitor.
