HANDHELD DEVICES AND RELATED METHODS
First Claim
1. A handheld device, comprising:
- a head portion comprising at least one rotary mechanism that comprises at least first and second rotational components and at least a first counter-rotational mechanism that operably engages at least the first and second rotational components, wherein at least one of the rotational components is configured to rotate at least partially around a rotational axis and comprises at least one surface that is configured to rotate substantially non-perpendicular to the rotational axis, which surface comprises at least one implement;
at least one drive mechanism component or portion thereof that operably engages, or is configured to operably engage, one or more of the rotational components and/or the first counter-rotational mechanism such that when the first rotational component rotates in a first direction and the second rotational component rotates in a second direction; and
,a handle portion operably connected or connectable to the head portion.

Abstract
The invention relates to devices including rotary units and rotary mechanisms that are suitable for use in numerous applications. Rotary units typically include rotational components that are configured to rotate. In some embodiments, for example, multiple rotary units are assembled in rotary mechanisms such that neighboring pairs of rotational components counter-rotate or contra-rotate relative to one another during operation of the rotary mechanisms. Rotational components generally include one or more implements that are structured to perform or effect one or more types of work as the rotational components rotate relative to one another in a given rotary mechanism. In certain embodiments, implements are configured to rotate and/or to effect the movement of other components as rotational components rotate.

40. A method of rotating an implement, the method comprising:
-
providing at least one handheld device that comprises; a head portion comprising at least one rotary mechanism that comprises at least first and second rotational components and at least a first counter-rotational mechanism that operably engages at least the first and second rotational components, wherein at least one of the rotational components is configured to rotate at least partially around a rotational axis and comprises at least one surface that is configured to rotate substantially non-perpendicular to the rotational axis, which surface comprises at least one implement; at least one drive mechanism component or portion thereof that operably engages, or is configured to operably engage, one or more of the rotational components and/or the first counter-rotational mechanism; and a handle portion operably connected or connectable to the head portion; and
,rotating the first rotational component rotates in a first direction and the second rotational component rotates in a second direction, thereby rotating the implement.
