Abstract: A cartridge razor sharpening device is provided. The sharpening device is configured to sharpen blades of cartridge razors, allowing for extended life and use. The device may operate to either slide over the blades to sharpen the blade edge, or may allow the blades to slidably move on the cartridge over the sharpening device. In some embodiments, a blade adjustment mechanism may be utilized to adjust a position of the blades after sharpening.

Abstract: A hand held heat-applying shaving device made up of body with a shape approximating that of a rectangular prism and having a first panel of stone such as granite and a second mating panel of metal such as titanium. In use the device is heated by immersion in hot water and the surface of the metal panel is then place against the face or other body part to be shaved. Shaving is achieved by means of a replaceable spring steel shaving head and retainer combination that protrudes from the top edge of the body and can be either single sided or double sided.

Abstract: A computer-aided method for implementing at least one synthetic investment fund.

Abstract: A razor comprises a body member, an elongate handle attached to the body member, a blade mounted to the body member, the blade having an exposed, cutting edge, and a cleaning and/or sharpening device slidably secured to the body member for slidingly engaging the blade essentially along the entire cutting edge thereof. An actuator element is operatively connected to the cleaning and/or sharpening device for enabling an operator to shift the cleaning device parallel to the edge of the blade. The cleaning device includes an elongate strip which slidingly contacts the blade along the exposed, cutting edge during a stroke of the actuator element.

Abstract: A cutting element comprises at least one cutting member, a handle arranged for holding the cutting member, and a casing surrounding the cutting member so that in an operative position a cutting blade of the cutting member is exposed while in an inoperative position it is confined in the casing, the casing being movable relative to the cutting member so as to sharpen the blade of the cutting member.

Abstract: An improved cutter head design for powered shavers, resembling the blade configuration of reel type lawnmowers. Elongated blades are mounted at intervals around a rotatable cutter assembly, with the width of the blades oriented radially. The axis of blade rotation is parallel to the skin being shaved. A thin, semi-flexible perforated screen covers part of the cutter assembly. Hair inserted through the screen is cut by the rotating blades against the screen material. This design allowa a toric (barrel-like) head shape, unlike the current reciprocating or rotary types, which require straight or flat shapes, respectively. A toric shape, is convex on two axes, providing a better match for the difficult facial curves at the jaw/neck junction. Difficulty in that area is where many would-be electric shaver users give up and return to the use of razor blades. Self-cleaning and self-sharpening mechanisms are described, which are made practical by this design. These increase convenience, effectiveness, and cutter life.
