A roller assembly for an electric razor includes a generally cylindrical roller driven by a drive arrangement to rotate about a central axis. The roller supports a number of blades, each having a cutting edge externally exposed and extending parallel to the central axis. Each blade moves across the skin of a user so as to slice through hair projecting from the skin of the user. The roller assembly further includes at least one filament wound in a helical path around the roller such that a gap between adjacent portions of the filament along the cutting edges is no more than about 8 millimeters.
