The haircutting scissors of the Joewell SPM Black series are conceived for professional use. The blades have been manufactured using a powder metallurgical process, resulting in a hardness 12 times that of regular metal. The handle shape conforms to the ergonomics of the hand in different styling techniques, and a protective silicone coating additionally helps to avoid fatigue symptoms. Using ion plating, the scissors are coated in black and are thus particularly abrasion-resistant.
