a weight portion comprising a through bore; and

a cam comprising a top portion, a keyed bore, a neck, and a base having a long side with a first length and a short side with a second length,

wherein the weight portion comprises a pair of hooked edges,

wherein the first length is greater than the second length,

wherein the neck is disposed within the through bore, and

wherein the keyed bore is sized to receive a tool.

2. The slidable weight assembly of claim 1 , wherein the through bore has a first diameter, wherein the top portion has a second diameter, and wherein each of the second diameter, the first length, and the second length is greater than the first diameter.

3. The slidable weight assembly of claim 1 , wherein the weight portion is composed of a first material having a first density, wherein the cam is composed of a second material having a second density, and wherein the first density is greater than the second density.

4. The slidable weight assembly of claim 3 , wherein the weight portion is composed of a tungsten alloy and wherein the base is composed of a polymeric material.

5. The slidable weight assembly of claim 1 , wherein the through bore comprises a keyed opening, wherein the top portion is shaped to fit within the keyed opening, and wherein turning the cam reversibly locks the weight portion to the cam.

6. The slidable weight assembly of claim 5 , wherein the keyed opening comprises a pair of extensions extending inwards from a lower surface of the weight portion.

7. The slidable weight assembly of claim 6 , wherein at least a part of the top portion rests on the extensions when the weight portion is reversibly locked to the cam.

8. A slidable weight assembly comprising:

a weight portion comprising a through bore; and

a cam comprising a top portion, a keyed bore, a neck, and a base having a long side with a first length and a short side with a second length,

wherein the first length is greater than the second length,

wherein the neck is disposed within the through bore,

wherein the keyed bore is sized to receive a tool, and

wherein the base has a shape selected from the group consisting of oval and eye-shaped.

9. A slidable weight assembly comprising:

a weight portion comprising a through bore;

a retainer ring, and

a cam comprising a top portion, a keyed bore, a neck, and a base having a long side with a first length and a short side with a second length,

wherein the first length is greater than the second length,

wherein the neck is disposed within the through bore,

wherein the keyed bore is sized to receive a tool.

10. The slidable weight assembly of claim 9 , wherein the weight portion comprises a ring-shaped recess sized to receive the retainer ring.

11. A golf club head comprising:

a body comprising a first rail and a second rail that are spaced from, and extend parallel to, one another; and

the slidable weight assembly of claim 1 ,

wherein the first rail and second rail form a channel having a floor with a first width and an upper opening with a second width,

wherein the first width is greater than the second width,

wherein the base is disposed within the channel,

wherein the neck extends through the upper opening,

wherein a majority of the weight portion is disposed above the first and second rails,

wherein the slidable weight assembly is movable between the first and second rails when the long side of the base is oriented so that it is parallel with the first and second rails, and

wherein turning the cam by 45 to 90 degrees reversibly fixes the slidable weight assembly to the first and second rails.

12. The golf club head of claim 11 , wherein the golf club head comprises a recessed area, and wherein the first and second rails are disposed within the recessed area.

13. The golf club head of claim 12 , wherein the recessed area is in communication with a weight port, and wherein the slidable weight assembly is sized to fit within the weight port to access the first and second rails.

14. The golf club head of claim 11 , wherein at least one of the first and second rails comprises an inner wall that forms an angle with the floor, wherein the angle is less than 90°.

15. The golf club head of claim 13 , wherein the angle is between 45° and 85°.

16. The golf club head of claim 14 , wherein the angle is approximately 70°.

17. The golf club head of claim 11 , wherein at least one of the first and second rails has a thickness of less than 0.100 inch.

18. The golf club head of claim 11 , wherein the first and second rails are spaced from one another by a distance of between 0.500 and 1.00 inch.

19. The golf club head of claim 11 , further comprising a pair of small rails extending from a lower surface of the weight portion, wherein the small rails rest against, and space the lower surface from, the first and second rails.
