a shaving assembly extending from said second end of said main body and comprising a non-cutting surface for engaging ends of said first finger and said second finger when said fingers are in said openings thereby providing points of contact with the said user's hand and a cutting surface, said main body and said shaving assembly are constructed and arranged for length adjustment of said shaving assembly extending from said main body; and

a leverage bar extending from said first end of said main body, said leverage bar for engaging said user's hand when said fingers are in said openings thereby providing points of contact with the said user's hand.

2 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , further including,

a vertical locking assembly constructed and arranged to engage with said user engagement member; and

a horizontal locking assembly constructed and arranged to engage with said main body and said shaving assembly.

3 . The proprioceptive shaver for shaving one or more portions of a body according to claim 2 , wherein said vertical locking assembly comprises:

a locking assembly body pivotably connected to a lower portion of said user engagement member via a rod, said locking body comprising a locking surface configured to engage with a surface of an upper portion of said user engagement member when in a locked position.

4 . The proprioceptive shaver for shaving one or more portions of a body according to claim 2 , wherein said horizontal locking assembly comprises:

a locking lever pivotably connected to said main body via a rod for traversing said horizontal locking assembly from a locked position to an unlocked position or from an unlocked position to a locked position; and

a locking body operatively connected to said locking lever, said locking body having a cam locking surface constructed and arranged to engage with said shaving assembly when said locking lever is rotated to said locking position.

5 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein said cutting surface includes one or more razor blades.

6 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein said shaving assembly includes a removable cartridge defining said non-cutting surface and said cutting surface, said cutting surface having one or more razor blades.

7 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein said leverage bar has a surface for contact of an area underneath the metacarpophalangeal joint of said first finger or said second finger of said user's hand.

8 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein an upper portion and a lower portion of said user engagement member provides for said height adjustment, said upper portion partially defining said first and second openings, and configured to engage with back or dorsal side surfaces of said first finger and said second finger of said user's hand when in use, and said lower portion partially defining said first and second openings, and configured to engage with palmer surfaces of said first finger and said second finger of said user's hand when said fingers are in said openings.

9 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein said first opening and said second opening are formed as two partially open ring-shaped structures.

10 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein said shaving assembly further comprises a shaft extending from said second end, said shaft configured to be movable relative to said main body, thereby providing for said length adjustment of said shaving assembly.

11 . The proprioceptive shaver for shaving one or more portions of a body according to claim 10 , wherein said shaving assembly shaft is sized and shaped to fit and move within an interior region of said main body.

12 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein said shaving assembly is positioned at an angle relative to said main body.

13 . The proprioceptive shaver for shaving one or more portions of a body according to claim 1 , wherein an upper portion and a lower portion of said user engagement member provides for said height adjustment, said upper portion partially defining said first and second openings, and configured to engage with back or dorsal side surfaces of said first finger and said second finger of said user's hand when in use, and said lower portion partially defining said first and second openings, and configured to engage with palmer surfaces of said first finger and said second finger of said user's hand when said fingers are in said openings.

14 . A proprioceptive shaver for shaving one or more portions of a body comprising:

a user engagement member comprising a first opening and a second opening;

a main body extending in a perpendicular direction from said user engagement member, and having a first end, a second, opposing end, and an interior passageway, said main body having a longitudinal axis arranged in a parallel orientation relative to a center axis of said first opening and a center axis of said second opening, said main body and said user engagement member are constructed and arranged for height adjustment of said first opening and said second opening;

a shaving assembly comprising an elongated shaft terminating in a non-cutting surface for engaging ends of said first finger and said second finger when said fingers are in said openings, said elongated shaft inserted within said interior passageway, with said non-cutting surface extending out from said interior passageway and said second end to allow a distal inferior phalange of a first finger of a user's hand and a distal inferior phalange of a second finger of said user's hand to rest on said non-cutting surface when in use; and

a leverage body positioned on said first end of said main body, said leverage bar for engaging said user's hand when said fingers are in said openings;

wherein, when placed on said user's hand wherein said user's first finger is inserted within said first opening and a distal inferior phalange of said first finger rests on said non-cutting surface and said user's second finger is inserted within said second opening and a distal inferior phalange of said second finger rests on said non-cutting surface, said proprioceptive shaver simultaneously contacts multiple areas of said user's hand.
