A single-blade razor apparatus and methods are for manufacturing the same. A razor apparatus includes a handle and a head pivotably mounted on the handle. The head includes a rear side including an aperture for receiving a single blade, as well as a front side through which a cutting edge of the blade is exposed during use. An upper portion and a lower portion of the head form the aperture. The lower portion physically interfaces with the upper portion so that a front region of the upper portion is physically supported by the lower portion. In a particular implementation, the lower portion includes several protruding latches proximate the front side of the head, which respectively mate with recesses formed in the upper portion. Alternatively, the latches are formed in the upper portion and respectively mate with recesses formed in the lower portion.

Systems, devices, and methods for applying machine learning to provide feedback related to a personal care device are described. Embodiments of the systems, devices, and methods may identify data from a device such as a razor comprising a plurality of sensors on a razor, predict one or more features such as shaving features based on the data using a machine learning model trained using data from the plurality of sensors, and provide shaving feedback based on the one or more features such as shaving features. Embodiments of the systems, devices, and methods may train a machine learning model, execute a trained machine learning model, capture and/or process data for the machine learning model, provide feedback based on the output of the trained machine learning model, or combinations thereof.

A handle. The handle can have a main body and a first substantially flat arm having a first distal end and a first proximal end defining a first arm opening can be coupled to a first location of the main body. A second substantially flat arm having a second distal end and a second proximal end defining a second arm opening, can be coupled to a second location of the main body. The first and second distal ends can be in spaced relationship and have pivotally coupled therebetween a pivoting head having a trapezoidal prism shape.

A razor cartridge comprising a housing extending along a longitudinal axis. The housing comprises a leading longitudinal side and a trailing longitudinal side. A cutting member mounting portion provided in between the leading longitudinal side and the trailing longitudinal side. Three or more substantially parallel cutting members are disposed in the cutting member mounting portion in a shaving direction of the razor cartridge. At least one of the three or more cutting members comprises a blade support. The blade support comprises a blade mounting portion disposed on an inner surface of the respective blade support that, in use, faces away from a shaving plane. A blade attached to the blade mounting portion. The cutting members are disposed to define a plurality of inter-blade spans between cutting edges of the blades. The trailing longitudinal side of the housing does not comprise a skin care element.

A blade carrier assembly with a blade carrier having a blade platform at a first end. A tab extends from the blade platform to a second end. A blade is mounted to the blade platform. The blade a cutting edge. The tab has a crest configured to engage a handle. The crest is positioned between a pair of angled surfaces of the tab.

A precision shaving razor with low cost assembly. A bridge is unitarily molded having a leading platform, a handle attachment mechanism and first and a second cross member each molded to extend substantially perpendicularly to the leading platform. A plurality of base members is each unitarily molded to have a first peg and a second peg for attachment to the cross pieces. A plurality of blade covers each unitarily molded. A razor blade is sandwiched between each blade cover-base pair. In some instances, the blade covers are molded to have hard stops to facilitate precise blade position. In some cases, the bases define angular wash through channels and blade guards spaced to facilitate wash through. In some cases, the skin contacting surfaces of the razor are textured during molding to have a glide improving texture.

A tapered razor assembly arranged to be removably inserted into a slot disposed on a static blade member of a scissors. The tapered razor assembly includes a razor blade having a base extending from a back end to a tip end, the razor blade having a pair of side surfaces extending from the base, the pair of side surfaces arranged to terminate at a cutting edge, the cutting edge tapering from the base end to the tip end, a guard member fixedly secured to one of the pair of the surfaces, the guard having a guard end, a base, and a tip, and a cover member fixedly secured to one of the pair of side surfaces, the cover having a base and a tip, wherein the guard member and the cover member sandwich the razor blade.

A safety razor including a handle; a base plate having an upper surface; and a top cap having a lower surface. The top cap configured to be secured to the base plate to hold a removeable double-edged razor blade between the upper surface and the lower surface, with the handle extending from the joined base plate and top cap for use in manipulating the joined base plate and top cap.

Shear razor devices for cutting and styling hair with a shear razor device using a hair shear functionality, a razor functionality, or both. The shear razor device includes a thumb member having a grip portion and a blade portion, and a finger member having a grip portion and a blade portion. The thumb member and the finger member are pivotally attached to each other for the hair shear functionality. The blade portion of the finger member may be comprised of a flat inner wall joined with a tapered outer wall at lower portions thereof to form an inner blade of the finger member as part of the hair shear functionality. The flat inner wall and the tapered outer wall may be disjoined at upper portions thereof to form an elongated groove configured to removably accept and secure a razor therein for the razor functionality.

The present disclosure provides a razor accessory with a camera to assist the user of a shaving razor, which razor accessory is configured to be mechanically attached to the shaving razor. The razor accessory may be provided with sensors to track the shaving movements of a user. The present disclosure also provides an application for a wearable computer device to track the shaving movements of a user. The razor accessory and/or the wearable computer is communicatively connected to a vendor platform via an Internet-of-Things (IoT) gateway, which may provide feedback to assist and optimize the user's shaving experience.
