A razor is provided, including a handle to be gripped by a user, a power generation unit disposed in the handle and configured to provide rotational power, a drive transmission unit coupled to the power generation unit and configured to be rotated by the rotational power, a cartridge including a blade housing on which one or more blades are seated, and a drive receiving unit formed at one side of the cartridge and configured to be in contact with the drive transmission unit to cause the blade housing to perform a linear movement in response to rotation of the drive transmission unit, wherein the cartridge is coupled to the handle such that the cartridge is pivotable about a pivot axis perpendicular to a rotational axis of the power generation unit, and wherein the pivot axis intersects the drive transmission unit.

Razor having a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member. Each sawing tooth has a tooth tip and tooth edges mutually connected via the tooth tip. The hair-severing member is mounted for sawing through hairs present on the skin by means of the sawing teeth by moving each sawing tooth in a local direction of extension of the hair-severing edge at the position of the respective sawing tooth. A drive is coupled to the hair-severing member for driving the hair-severing member such that the sawing teeth move with an average velocity larger than or equal to 10 m/s. The spacing between the tooth tips of two successive sawing teeth is between 20 μm and 150 μm.

A shaving razor. A first and second blade assembly each have a cutting edge oriented to shave in the same direction. The first and second blade assemblies are each displaceable along a respective first and second path substantially parallel to their cutting edge. First and second linkages couple together a first ends and second ends respectively of the first and second blade assembly. The linkages are configured such that a displacement of the first blade assembly in a first direction along the first path causes a displacement of the second blade assembly in an opposite direction along the second path. Other embodiments are also described and claimed.
