  • Patent number: 7975387
    Abstract: To provide a hair cutting device permitting the user to really know the remaining hair length without having to do trial cuts, a hair cutting device (1) with hair length indicator means (4) is proposed, wherein the hair length indicator means (4) comprises a fixed delimiter (5) and at least one movable delimiter (6) being movable with respect to the fixed delimiter (5), such that the hair length is indicated by the distance (D) between the fixed (5) and the at least one movable delimiter (6). Preferably, the hair length indicator means (4) comprises more than one movable delimiter (6, 7), all movable delimiters (6, 7) being movable in circumferential direction and functionally couplable with a comb unit (19, 20) such that a change between movable delimiters (6, 7) is caused by attachment of the comb unit (19, 20) to the hair cutting device (1).
