Abstract: A grooming device includes a cutting arrangement for cutting hair that grows in or at the nostrils and/or the ear channels of the head of a human being. This cutting arrangement includes a shielding element and a cutting element including a driving member supported in the shielding element only for rotation about an axis relative to the shielding element. The cutting arrangement is mounted on a housing of the device for movement in unison into and out of the housing between an extended and a retracted position and back. In the extended position, a lug received, after turning of the shielding element about the axis, in a confining recess of the housing, arrests the cutting arrangement in its extended position. Alternatively, a pin passing through a C-shaped through recess in the housing to the exterior of the latter serves the same purpose.
