Abstract: The present invention relates to a cutter system for an electric shaver and/or trimmer, comprising a pair of cooperating cutter blades each having at least one row of comb-like cutting teeth, wherein one of said cutter blades is stationary and the other one is movable relative to the stationary cutter blade along a cutting surface defined between said cooperating cutter blades, said cutting teeth each having pairs of lateral cutting edges tapering towards a tooth tip, wherein said tooth tips of at least one of the cooperating cutter blades are provided with a flattened, beveled tip surface.

Abstract: A hair cutting kit comprises a cutting unit and a comb. The comb comprises a row of comb teeth. Some or all of the comb teeth comprise, on an outer face, a skin surface configured to glide on a user's skin, a feeding surface configured to feed hairs towards the cutting unit, and a transition surface between the skin surface and the feeding surface. The skin surface has a first surface contour line having a first radius of curvature, the feeding surface has a second surface contour line having a second radius of curvature, and the first radius of curvature is greater than the second radius of curvature.

Abstract: A hair cutting kit comprises a handle, a first trimmer head configured for reversibly releasable attachment to the handle , a second trimmer head configured for reversibly releasable attachment to the handle, and a comb implement comprising at least one row of comb teeth and a mechanical interface operative for reversibly releasable attachment of the comb implement to the first trimmer head and for reversibly releasable attachment of the comb implement to the second trimmer head.
