a shank extending from the handle and including a tip,
wherein the butt includes a first recess located at a center of the butt and having a shape corresponding to the tip and a plurality of second recesses arranged around the first recess in an annular arrangement, and
wherein each of the second recesses has the shape.

2. The screwdriver of claim 1 , wherein the first recess and the second recesses are recessed into a material of the butt.

3. The screwdriver of claim 1 , wherein the first recess has a first square shape and the second recesses have second square shape, wherein the second square shape is different than the first recess square and wherein the tip of the shank has a square drive.

4. The screwdriver of claim 1 , wherein the first recess has a first size and each of the second recesses have a second size that is different than the first size.

5. The screwdriver of claim 4 , wherein the second size is smaller than the first size.

6. The screwdriver of claim 1 , wherein the handle is formed from a first material and a second material that is different than the first material.

7. The screwdriver of claim 6 , wherein the first recess is located on the first material and the second recesses are located on the second material.

8. The screwdriver of claim 6 , further comprising a bore extending through the first material and the second material.

9. The screwdriver of claim 6 , further comprising an overmold on the handle.

10. The screwdriver of claim 6 , further comprising a neck formed of the first material.

11. The screwdriver of claim 10 , wherein the neck includes a bore with one or more grooves extending radially outward from the bore and wherein the shank includes a rear portion opposite the tip, the rear portion including one or more radially outward-extending splines, and wherein the rear portion is arranged in the bore and the one or more splines are arranged in the one or more grooves.

12. A screwdriver comprising:
a handle formed from a first material and a second material that is different than the first material, the handle including a butt; and
a shank extending from an end of the handle opposite the butt and including a tip,
wherein the butt includes a first element located in the first material and having a shape corresponding to the tip and a plurality of second elements-located in the second material and spaced around the first element,
wherein the first element has a first size and each of the second elements have a second size that is different than the first size, and
wherein each of the second elements has the shape.

13. The screwdriver of claim 12 , wherein the first element and the second elements are recessed into the butt.

14. The screwdriver of claim 12 , wherein the plurality of second elements are arranged around the first element in an annular arrangement.

15. The screwdriver of claim 12 , further comprising knurling on the shank, wherein the shank comprises a metal material, and wherein the handle comprises a core plastic material and a plastic material extending around the core plastic material.

16. A screwdriver assembly comprising:
a first screwdriver including
a first handle including a first butt,
a first shank extending from the first handle and including a first tip; and

a second screwdriver including
a second handle including a second butt,
a second shank extending from the second handle and including a second tip, wherein the first butt includes a first element having a first shape corresponding to the first tip and a plurality of second elements arranged around the first element,

wherein each of the second elements has the first shape,
wherein the second butt includes a third element having a second shape corresponding to the second tip and a plurality of fourth elements arranged around the third element,
wherein each of the fourth elements has the second shape,
wherein the first element has a first size that is different than a second size of each of the second elements and wherein the third element has a third size that is different than a fourth size of each of the fourth elements, and
wherein the first tip has a different shape than the second tip, and the second shape is different than the first shape.

17. A screwdriver comprising:
a handle including a butt; and
a shank extending from the handle and including a tip,
wherein the butt includes a first recess having a shape corresponding to the tip and a plurality of second recesses arranged around the first recess, and
