ABSTRACT:
A hand-held implement, is provided with a body including an elongated snap-fit post and an elongated snap-fit cartridge housing. The snap-fit cartridge housing includes a coaxial recessed groove and readily snap-fits into the body of the pen by the resilient engagement of the tip of the snap-fit post into the coaxial recessed groove of the snap-fit cartridge housing. The cartridge housing can be readily removed from the body of the pen and replaced with another cartridge housing inserted in its place. The body of the implement has external surfaces which define contours which match and ergonomically engage the surfaces of a user's thumb and fingers when the user grasps the implement, so as to provide a large surface area of contact between the user's hand and the implement. The increased area of contact between the user's hand and the implement, compared to traditional designs, decreases the required level of applied unit area pressure, and also provides for greater control consequently facilitating manipulation of the implement. The exterior of the implement is sufficiently small so that, while in use, the body of the implement does not extend outside or beyond the hand of the user. Such a hand-held implement may advantageously be used in all manually performed activities utilizing hand-held instruments, including for example, writing, painting, cutting, soldering, digitalizing and applying cosmetics.
