There is disclosed a cutting unit (14, 60, 80, 100) for a hair cutting device (10), comprising: a blade carrier (16) carrying a cutting blade; a guard (18) comprising: a blade-facing surface engaging the cutting blade at a cut location; a planar guard contact surface (30) for contacting skin of a user, wherein the guard contact surface (30) is angled with respect to the blade-facing surface; and a guard extender (40, 70, 90) separate from the guard (18), wherein the guard extender (40, 70, 90) comprises a planar extension contact surface (46, 76, 96) configured to cooperate with the guard contact surface (30) to provide an extended contact zone (50) across the guard (18) and the guard extender (40, 70, 90) for contacting skin of a user. The blade-facing surface and the guard contact surface (30) converge towards a tip of the guard, wherein a cutting direction extends along the guard contact surface (30) towards the tip. The guard extender (40, 70, 90) is configured so that the extension contact surface (46, 76, 96) is rearward of the guard contact surface (30) with respect to the cutting direction X. The extension contact surface (96) has a transverse extent along an axis perpendicular to the cutting direction, and wherein there is a gap along the cutting direction X between the guard contact surface and at least a transverse portion of the extension contact surface. The extended contact zone may provide for improved stability and reliable orientation of the cutting unit for cutting while limiting material use.

One embodiment provides a guide comb having a holdable extension including: a central portion including; a plurality of teeth extending at one end thereof; and the holdable extension extending from an opposite end with respect to the plurality of teeth; wherein a lower face of the central portion includes an attachment mechanism to reversibly secure a hair clipper. Other aspects are described and claimed.

A blade assembly for a hair cutting apparatus is provided having a first blade having teeth extending along a first blade edge, a second blade positioned proximate the first blade and having teeth extending along a second blade edge parallel to the first blade edge and offset from the first blade edge by a blade gap, a yoke adapted to convert motion of a drive mechanism into reciprocation of the second blade with respect to the first blade, a spring having a spring base and at least one spring arm coupled to one of the yoke and second blade, the spring arm reciprocating with the second blade with respect to the first blade, wherein the spring arm applies a biasing force on the second blade toward the first blade to maintain the first and second blades in an operational condition when separated from the hair cutting apparatus.

A guard element (4) for use in a hair cutting unit as a guard of a movable hair cutting element of the hair cutting unit has a disc-shaped base (10) and an annular wall (20) comprising a main part (21) extending from the periphery of the base (10), and a flange-shaped part (22) comprising an outwardly bent section (24). The annular wall (20) is reinforced on the basis of at least one of a design where a smallest inner periphery of the flange-shaped part (22) has a diameter which is smaller than a diameter of a largest inner periphery of a straight section (23) of the main part (21) connected to the periphery of the base (10), and a design where a free end section (25) of the flange-shaped part (22) is at least partially bent. In an embodiment, at least a portion of the main wall part (21) of the guard element (4) tapers inwardly in a direction along a central axis (11) of the disc-shaped base (10), from the disc-shaped base (10) to the flange-shaped wall part (22), such that the flange-shaped wall part (22) is enlarged with respect to a flange-shaped wall part (22) of a guard element (5) not having the tapered shape of the main wall part (21), resulting in increased stiffness and an increased resonant frequency of the guard element (4).
