Abstract

Hair trimmers, for example hair trimmers particularly suited for trimming nose hair. One aspect includes at least one movable blade and at least one shell having an interior surfaces at least one hole extending through the shell, and an interior cutting edge. The movable blade is hingedly connected to a movable blade hinge comprising a longitudinal axis. The shell, movable blade hinge and movable blade are positioned such that the cutting edge of the blade travels close to or along a portion of the interior surface of the shell and precedes the hinge such that resistance to the movement of the blade edge, such as that provided by a hair contacting the blade edge, will tend to wedge the blade more tightly between the hinge and the shell thereby increasing the contact pressure between the movable blade and the stationary surface. The cutting edge can also be urged toward the interior surface by centrifugal force.
