5. The knob/handle according to claim 2 , wherein said inner cage further comprises a base having at least one protruding leg and a plurality of spaced upwardly extending walls, each having a bulbous end.

6. The knob/handle according to claim 2 , further comprising a runner connecting the at least two sprag teeth are initially connected to each other, said runner being configured to break after an initial use of the knob/handle.

7. The knob/handle according to claim 2 , wherein

said outer cage further comprises a base having a plurality of spaced upward extending cage wails each having a bulbous end;

said inner cage further comprises a base having at least one protruding leg and a plurality of spaced upwardly extending walls, each having a bulbous end; and

wherein said at least two sprag teeth pass through said walls in said inner and outer cage to contact inner wall surfaces of said receiving cavity.

8. The knob/handle according to claim 1 , wherein the locking mechanism comprises:

a lock having a pawl, said lock being slidably positioned in the handle body; and

a plurality of teeth positioned around the hub, said pawl engaging at least one of said plurality of teeth when the lock is in slid into the locked position.

9. A device for a assisting in the rotation of a kitchen device having a rotary motion, the device comprising:

a body;

a sprag clutch mechanism disposed within the body; and

a means for disposing the sprag clutch mechanism into communication with rotary parts of the kitchen device, such that said sprag clutch mechanism enables one way rotation of the rotary parts of the kitchen device in a pre-determined rotation direction; and

a locking mechanism configured to lock the body and enable rotation of the connected rotary parts of the kitchen device in an opposite direction than that of the predetermined rotation direction.

10. The device according to claim 9 , wherein said body comprises a handle.

11. The device according to claim 9 , wherein said sprag clutch mechanism comprises:

an outer cage positioned within a receiving cavity of the handle;

an inner cage positioned within the outer cage; and

at least two sprag teeth positioned within the receiving cavity such that said teeth contact inner wall surfaces of said receiving cavity, said sprag teeth having a geometric configuration enabling rotation of the rotary parts of the kitchen device in a single predetermined rotation direction of clockwise or counterclockwise.

12. The device according to claim 11 , wherein said outer cage further comprises a base having a plurality of spaced upward extending cage walls each having a bulbous end.

13. The device according to claim 11 , wherein said inner cage further comprises a base having at least one protruding leg and a plurality of spaced upwardly extending walls, each having a bulbous end.

14. The device according to claim 11 , further comprising a runner connecting the at least two sprag teeth, said runner being configured to break after an initial use of the knob handle.

15. The device according to claim 11 , wherein,

said outer cage further comprises a base having a plurality of spaced upward extending cage walls each having a bulbous end;

said inner cage further comprises a base having at least one protruding leg and a plurality of spaced upwardly extending walls, each having a bulbous end; and

wherein said at least two sprag teeth pass through said walls in said inner and outer cage to contact inner wall surfaces of said receiving cavity.

16. The device of according to claim 11 , wherein said means for disposing the sprag clutch mechanism into communication with rotary parts of the kitchen device comprises a hub disposed within the body and having one end in communication with the sprag clutch mechanism and an opposing end configured for connection to the rotary parts of the kitchen device.

17. The device according to claim 9 , wherein the locking mechanism comprises:

a lock having a pawl, said lock being slidably positioned in the handle body; and

a plurality of teeth positioned around the hub, said pawl engaging at least one of said plurality of teeth when the lock is in slid into the locked position.
