Abstract: A device and methodology for flossing teeth. The device includes a body having a first arm and a second arm. The first and second arms connect at a vertex. The first and second arms extend distally from the vertex and cross over each other at a crossing over region, so that transverse movement of the first arm relative to the second arm between the vertex and the crossing over region causes an opposite transverse movement at distal ends of the first arm and the second arm. A length of dental floss is coupled between the distal ends of the first arm and the second arm at first and second attachment positions. When in a neutral position with no forces applied to the first arm and the second arm, the distance between the first and second attachment positions is smaller, and the dental floss looser, relative to when the first and second arms are squeezed together between the vertex and crossing over region such that distance between the first and second attachment positions is larger, and the dental floss tauter.

Abstract: A knife has a handle with an enlarged proximate end grip portion having ribbed and unribbed surfaces. The handle has oppositely disposed thumb receiving concave unribbed surfaces at the distal end for alternate pinch-grip functions. The knife blade has a cutting edge that extends proximately below and adjacent the enlarged grip portion, and is proximately disposed with respect to the thumb receiving pinch-grip concave surfaces. The knife provides diverse impaired grip cutting functions with comfort and with fatigue.
