Abstract
A mechanical thinning razor includes a shank, a handle, a blade, a bladeguard, a driving member and a sliding member. When pushing an external surface of the driving member toward a hollow midsection of the shank, the bevel of the driving member forces the sliding member to move longitudinally over a distance that corresponds to a width of exposed segments or non-exposed segments, thereby doubling the working life of the blade.
