A shaving apparatus having a head portion intended for contact with a skin surface to cut hairs growing therefrom. The head portion may include a cylindrical screen and a cutting component located within a cavity defined by the cylindrical screen. The cylindrical screen includes a plurality of openings so that a user's hairs can pass therethrough to be cut by blades of the cutting component. The cylindrical screen may be rotatable about a rotational axis so that as the cylindrical screen is placed into contact with a skin surface and moved therealong, the cylindrical screen is made to rotate about the rotational axis. The shaving apparatus may include a brake sub-system to intermittently reduce a rotational velocity of the cylindrical screen.

A shaving unit (16) is disclosed comprising a housing (12), a guard (20) stationary relative to the housing (12), a cutting edge (22) arranged at a distance from the guard (20) and stationary relative to the housing, a hair-entry opening bounded by the guard and the cutting edge, and a drum (24) arranged within the housing, the drum (24) being configured to be driven rotatingly about a longitudinal axis thereof. A plurality of counter cutting edges (28) is arranged on the drum (24), wherein the counter cutting edges (28) cooperate with the cutting edge (22) during rotation of the drum (24) about the longitudinal axis (26) for shearing or cutting hairs when the shaving unit (16) is moved over a skin (30). The shaving unit (16) further comprises a lubricating arrangement (36) with a liquid reservoir (38) filled with a lubricant and with a feed mechanism (41) for supplying the lubricant from the liquid reservoir (38) to at least one of the counter cutting edges (28) for providing a lubricating film (42) thereto. The feed mechanism (41) comprises a lubricating element (39) arranged adjacent to the drum (24) in a position such as to engage the at least one counter cutting edge (28) during rotation of the drum (24) about the longitudinal axis (26).

A manually operated hair trimming device having a barrel which is rolled over hair to be trimmed. The barrel has at least one aperture through which hair is able to protrude. The device has a first cutting blade provided inside the barrel and a second cutting blade is associated with the barrel. In use, as the barrel is rolled over hair to be trimmed, hair protrudes through the at least one aperture and is cut by a shearing force between relatively moving first and second cutting blades.
