Abstract: A razor having a housing, a guard located at a front of the housing and a cap located at a rear of the housing. A skin contact plane is tangential to the guard and the cap. A blade couplet is disposed in the housing, the blade couplet being formed of a leading blade having a leading edge and a trailing blade having a trailing edge, both edges being directed towards the front of the housing and the leading blade being positioned between the guard and the trailing blade. There is a span of about 25 ?m to about 850 ?m between the leading edge and the trailing edge, the leading edge has an exposure of about 25 ?m to about 500 ?m below the skin contact plane, the trailing edge is positioned in line with or above the leading edge and has an exposure of about 150 ?m above the skin contact plane to about 300 ?m below the skin contact plane, and the difference in exposure between the leading edge and the trailing edge is equal to or less than the span between the leading edge and the trailing edge.

Abstract: A method of viewing a surface comprising taking at least a first image from a first position and a second image from a second position to allow for comparative analysis and diagnosis of the surface.

Abstract: A digital microscope for viewing the surface of an object comprises a housing having a proximal end and a distal end. The distal end forms an opening to the housing. A sensor that receives light reflected from the surface of an object is located towards the proximal end of the housing. The sensor converts the light to a digital image. A lens that focuses light reflected from the object onto the sensor is located within the housing between the sensor and the object to be viewed. A reflective member is located within the opening. In use, light is reflected from the object to the sensor and a portion of the reflected light is directed via the reflective member such that the surface of the object can be viewed simultaneously from two different directions.
