A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.

A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.

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.

A razor assembly includes a razor cartridge comprising at least one shaving blade, and a blade housing configured to receive the at least one shaving blade in a first direction; a cartridge connector coupled to the razor cartridge such that the razor cartridge is rotatable with respect to the cartridge connector about a rotational axis parallel to the first direction; and a razor handle, wherein the cartridge connector further comprises: at least two first cantilevers configured to provide a recovering force to the razor cartridge to restore the razor cartridge to a rest position; at least one second cantilever coupled to at least a part of the razor handle; and an upper wall covering the at least one second cantilever, wherein the at least one second cantilever is not exposed to an outside by the upper wall when viewed from a bottom side of the blade housing.

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 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 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.
