5. The screwdriver handle of claim 1 , wherein said base portion comprises at least one gripping indent feature.

6. The screwdriver handle of claim 1 , wherein said at least one arm is adapted to articulate from a first position planar to a longitudinal axis of said base portion to a second position transverse to said longitudinal axis of said base portion.

7. The screwdriver handle of claim 6 , wherein said at least one arm comprises two arms, and wherein said two arms are diametrically opposed to one another when in said second position.

8. The screwdriver handle of claim 1 , further comprising a pin connecting said at least one arm to said base portion.

9. The screwdriver handle of claim 1 , wherein said locking sleeve is adapted to engage said at least one arm, and wherein said locking sleeve is adapted to move along a longitudinal axis of said base portion.

10. The screwdriver handle of claim 1 , wherein said at least one arm comprises a pair of arms that are unconnected to one another.

11. The screwdriver handle of claim 1 , wherein said pair of arms are unconnected to one another.

12. A screwdriver handle comprising:

a base portion;

a pair of arms connected to said base portion, wherein said pair of arms are diametrically opposed to one another at a position transverse to a longitudinal axis of said base portion; and

locking means operatively connected to said base portion,

wherein a tip of each of said pair of arms comprises an indented lip adapted to engage said locking means.

13. The screwdriver handle of claim 12 , further comprising:

a spring member mounted around said base portion and adapted to engage said locking sleeve; and

a torsion spring connected to said base portion and each of said pair of arms,

wherein said locking sleeve is mounted around said base portion and is adapted to engage said pair of arms,

wherein said base portion comprises a catch, and

wherein said locking sleeve comprises a stop feature adapted to engage said catch.

14. The screwdriver handle of claim 12 , wherein said base portion comprises a hollow inner shaft chamber.

15. The screwdriver handle of claim 12 , wherein said base portion comprises at least one gripping indent feature.

16. The screwdriver handle of claim 12 , wherein said pair of arms are adapted to articulate from a first position planar to a longitudinal axis of said base portion to a second position transverse to said longitudinal axis of said base portion.

17. The screwdriver handle of claim 16 , wherein said pair of arms are diametrically opposed to one another when in said second position.

18. The screwdriver handle of claim 12 , further comprising a pin connecting said pair of arms to said base portion.

19. The screwdriver handle of claim 12 , wherein said locking sleeve is adapted to move along a longitudinal axis of said base portion.

20. A screwdriver handle comprising:

a base portion;

a pair of arms pivotally connected to said base portion;

locking means for locking said pair of arms in a first position planar to a longitudinal axis of said base portion, wherein a tip of each of said pair of arms comprises an indented lip adapted to engage said locking means;

first energy means for providing energy to said locking means to articulate from a locked to an unlocked position; and

second energy means for providing energy to said pair of arms to articulate from said first position planar to said longitudinal axis of said base portion to a second position transverse to said longitudinal axis of said base portion.
