initially gripping the golf club such that the center plane of the golf training apparatus is aligned with a center line of the trainee, as well as with a shaft of the golf club;
swinging the golf club in a backward direction; and
swinging the golf club in a forward direction until the swing is completed;
wherein the golf club is swung in a backward direction until only the first color region of the golf swing training aid is visible, and wherein the golf club is swung in a forward direction until only the second color region of the golf swing training aid is visible.
10. The method of claim 9, wherein swinging the golf club in the backward direction further comprises shifting the trainee’s weight from a foot located forward of the center line of the trainee to a foot located behind the center line of the trainee.
11. The method of claim 10, wherein swinging the golf club in the forward direction further comprises shifting trainee’s weight from the foot located behind the center line of the trainee to a foot located forward of the center line of the trainee.
12. The method of claim 11, wherein swinging the golf club in the forward direction is performed at least 5 times with a golf ball.
13. The method of claim 9, wherein swinging the club in the backward direction further comprises swinging the club in the backward direction until the hands of the trainee are at least chest high.
14. The method of claim 13, wherein swinging the golf club in the forward direction positions the golf club over a shoulder located forward of the center line of the trainee.
15. The method of claim 14, wherein swinging the golf club in the forward direction is performed at least 5 times without a golf ball.
16. The method of claim 9, wherein swinging the club in the backward direction further comprises positioning the golf club over a shoulder located behind the center line of the trainee.
17. The method of claim 16, wherein swinging the golf club in a forward direction further comprises brushing the golf club against a ground surface while the golfer observes the golf swing training aid changing from a first color to a second color.
18. The method of claim 9 wherein, when the swing of the golf club in the backward direction is completed, the trainee sees both type regions.
19. The method of claim 9 wherein, when the swing of the golf club in the forward direction is completed, the trainee sees both type regions.
20. The method of claim 18 wherein, when the swing of the golf club in the forward direction is completed, the trainee sees both type regions.
21. The method of claim 9 wherein the light weight three dimensional member is held between the forearms only by pressure applied at the forearms.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.

a body;
a blade element having a cutting edge and being rotatably mounted with respect to the body; and
a sharpening tool configured to be coupled to the body, the sharpening tool being selectively movable between a first position in which the sharpening tool is spaced from the blade element and a second position in which the sharpening tool contacts the blade element at or adjacent the cutting edge, the sharpening tool sharpening the cutting edge when in the second position and the blade element is rotated.
2. The cutting device of claim 1, further comprising:
