All-in-one blade. The new, ultimate cutting set is versatile and can be used for every haircut: for fringe looks in long hair, for incorporating supporting hair in extremely thick hair, for working out volume overlays with constant hair length, and for slicing and peeling long hairstyles for a fresh, healthy appearance. This prevents split ends. It is also suitable for cutting hair extensions and for working out and structuring short hair. For a smooth, harmonious course in the three positions, the adjustment lever integrated into the cutting set can be selected. The intensity of the cutting effect can be individually adjusted by the intermediate positions.
