An example electric shaver head is provided. The electric shaver head includes a shaver head housing, and at least one cutter assembly disposed in the shaver head housing. The electric shaver head includes two or more spacer elements positioned over the cutter assembly. The two or more spacer elements provide an offset distance from a top surface of the at least one cutter assembly to create stubble when shaving.

The present disclosure generally relates to instruments for neurotologic surgical procedures, and more particularly, instruments for shearing ear canal hairs having combined shearing, illumination, and vacuum functions. In certain embodiments, the instruments may further facilitate visualization of the ear canal during the shearing of ear canal hairs.

A rotary electric shaver includes a head connected to the main body. The head includes an outer blade part and an inner blade part. The inner blade part includes a plurality of inner blades and a base part in which the inner blades are disposed around the first axis, and the inner blades come into sliding contact with a sliding contact surface of the outer blade. In the outer blade, an outer area in which a first r-curved portion following a top part is circled and an inner area in which a second r-curved portion following the top part is circled are continuous, and the first r-curved portion is longer than the second r-curved portion.

Embodiments of the present disclosure disclose a cutting unit, a shaver head, and an electric shaver. The cutting unit is used in a shaver, and includes a support member having a rotation axis and cutting blades provided with cutting edges. The support member carries support legs in the cutting blades. Each cutting blade has a direction of movement during the rotation of the cutting unit around the rotation axis. Each of the cutting edges includes a first cutting edge and a second cutting edge. A curvature of the first cutting edge is greater than or equal to a curvature of the second cutting edge, and a distance from the first cutting edge to the rotation axis is greater than or equal to a distance from the second cutting edge to the rotation axis.
