Referring now to Figure 6, showing a schematic representation of a comparison between angles used in prior art blades and angles used in the blades of the invention, according to some embodiments of the invention. Blades 600 in prior art devices comprise a sharp edge having a 22 degree angle (two sharp sides of 11 degrees each) finishing in a sharp tip 602. In some embodiments, the sharp tip 602 is the first part of the blade that meets the hair being shaved and usually the sharp tip 602 is moved along the surface that is being shaved in order to shave the hair at the closest level in relation to the surface. Additionally, the blades 600 in the prior at devices are usually positioned at an angle of about 22 degrees in relation to the surface being shaved, when measured from a longitudinal axis of the blade 600. This causes the blade 600 to move at an angle of about 11 degrees in relation to the surface being shaved, when measured from a longitudinal axis of the blade 600.

In some embodiments, the blade 106 of the shaving device 100 is positioned so it is positioned at an angle of from about 1 degree to about 10 degrees in relation to the surface being shaved, when measured from a longitudinal axis of the blade 106. Optionally, the blade 106 of the shaving device 100 is positioned so it is positioned at an angle of about 5 degrees in relation to the surface being shaved, when measured from a longitudinal axis of the blade 106, as shown for example in Figure 6. In some embodiments, the blade 106 of the shaving device 100 is positioned so the tip of the blade is not being dragged along the surface that is being shaved, when the shaving device 100 is being used. A potential advantage of positioning the blade at an angle of about 5 degrees in relation to the surface being shaved, when measured from a longitudinal axis of the blade 106 and or not dragging the sharp tip of the blade 106 along the surface being shaved is that it potentially allows shaving non-tense surfaces (for example, body skin) securely.

Referring now to Figures 7A-7B showing a schematic representation of a bottom view of the shaving device and a side cross view of the shaving device, respectively, according to some embodiments of the invention. In some embodiments, the blades 204 of the shaving device 100 are positioned adjacent to the wheels 206.
