Abstract

A screwdriver comprises a handle including a butt and a shank extending from the handle and including a tip. The butt includes a first indicating element having a shape corresponding to the tip and a plurality of second indicating elements arranged around the first indicating element. Each of the second indicating elements has the shape.

First claim

What is claimed is:

1. A screwdriver comprising:
a handle comprising:
a first end;
a second end, the second end including an end surface;

a shank extending between the first end of the handle and a tip;
wherein the end surface includes a first recess having an edge defining an outline corresponding to the tip and a plurality of second recesses arranged around the first recess; and
wherein each of the second recesses has an edge defining an outline;
wherein the outline of the second recesses is smaller than the outline of the first recess.

2. The screwdriver of claim 1 , wherein the end surface is a curved surface and wherein the end surface is concave relative to the second end of the handle.

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

4. The screwdriver of claim 3 , wherein the end surface includes a first portion formed from the first material and a second portion formed from the second material.

5. The screwdriver of claim 4 , wherein the first recess is located on the first portion of the end surface and the second recesses are located on the second portion of the end surface.

6. The screwdriver of claim 1 , wherein the first recess has a first cross-shaped outline and the second recesses each have a second cross-shaped outline.

7. The screwdriver of claim 1 , the handle further comprising a hole extending through the handle such that a lanyard can extend through the handle.

8. The screwdriver of claim 1 , the shank further comprising a hex bolster such that a tool may be used to rotate the screwdriver via the hex bolster.

9. A screwdriver comprising:
a handle formed from a first material and a second material that is different than the first material, the handle including an end surface; and
a shank extending from a first end of the handle opposite the end surface and including a tip;
wherein the end surface includes a first element located in the first material and having a perimeter 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 perimeter length and each of the second elements have a second perimeter length that is different than the first perimeter length;
wherein the first element is one of a recess and a protrusion and wherein the plurality of second elements are protrusions.

10. The screwdriver of claim 9 , wherein the first perimeter length is greater than the second perimeter length.

11. The screwdriver of claim 9 , wherein the second elements each have the perimeter shape corresponding to the tip.

12. The screwdriver of claim 9 , wherein the first element is located at a center of the end surface.

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

14. The screwdriver of claim 9 , further comprising a neck formed of the first material.

15. A screwdriver assembly comprising:
a first screwdriver including:
a first handle including a first end and a second end, the second end including a first end surface;
a first shank extending between the first end of the first handle and a first tip; and

a second screwdriver including:
a second handle including a first end and a second end, the second end including a second end surface;
a second shank extending between the first end of the second handle and a second tip;

wherein the first end surface includes a first element having a first shape corresponding to the first tip and a plurality of second elements spaced around the first element and wherein the first element has a first size that is different than a second size of each of the second elements;
wherein the second end surface includes a third element having a second shape corresponding to the second tip and a plurality of fourth elements spaced around the third elements and wherein the third element has a third size that is different than a fourth size of each of the fourth elements;
wherein the first element is one of a recess and a protrusion and wherein the plurality of second elements are protrusions; and
wherein the third element is one of a recess and a protrusion and wherein the plurality of fourth elements are protrusions.

16. The screwdriver assembly of claim 15 , wherein each of the second elements has the first shape and each of the fourth elements has the second shape.

17. The screwdriver assembly of claim 15 , wherein the first tip has a different shape than the second tip.

18. The screwdriver assembly of claim 15 , wherein the first end surface includes a first portion and a second portion and the second end surface includes a third portion and a fourth portion.

19. The screwdriver assembly of claim 18 , wherein the first portion is formed from a first material and the second portion is formed from a second material and wherein the third portion is formed from the first material and the fourth portion if formed from the second material.
