Abstract: A comfortable way to daily remove inter-dental plaque would encourage dental hygiene and could improve health worldwide. The flossing by hand’ method is the most effect but its adoption is limited by the dexterity of the user especially among young and old people. Many efforts have been made to make flossing easier by extending floss from a device held outside the mouth, but most designs use a fixed, stretched, length of floss at the tooth. The method of use for these devices is dictated by the physical form of the device needed to mount the fixed stretched length of floss. But the goal of flossing devices is to emulate the ‘by hand’ method. This invention starts with the ‘by hand’ method and designs this device 1 to perform it. The “Loose Floss Method of Inter-dental Plaque Removal’ is strictly based on the ‘by hand’ method of flossing and provides a device 1 design exclusively to perform that method. closely without putting one's hands inside their mouth.

Abstract: Double handle knives and attachments to convert a knife to a double handle knife are described with secondary handles able to form an angle (a) between about 20 to 70 degrees between the long axis of the secondary handle and the long axis of the blade in a plane at about right angles to the blade. Embodiments describe fixed, rotatable, and indexable means for the angle of attachment of the secondary handle to the blade. Embodiments further describe reversible and permanent means of attachment. The placement of the secondary handle at the angle described allows for the optimal positioning of the hands for both controlling and assisting with the cutting of foods and other items.

Abstract: A double handle knife is described with the secondary handle rotatable upon a pivot post. In further embodiments: the secondary handle is mounted to the top of the blade at a fixed angle of 45 degrees (+ or ?25) degrees between the long axis of the secondary handle and the long axis of the knife blade; and attachments are described to convert single handle knifes into double handle knives functioning identical to those described above. A methods is described utilizing the double handle knife invention in any of its embodiments being gripped by the dominant hand on the primary handle, four fingers of the non-dominant hand being placed evenly upon the secondary handle with long axis thereof positioned at an angle of 45 degrees (+ or ?25) degrees to the long axis of the knife blade, the palm/or thumb of the same hand positioning the food item, both hands applying downward pressure and the food item being easily and accurately cut.
