a body member having a cavity that extends from an opening at a front end portion of the body member toward a back end portion of the body member;

a cutting member partially disposed in a first portion of the cavity; and

a first urging member portion disposed in a second portion of the cavity and a second urging member portion disposed in a third portion of the cavity;

wherein the first portion of the cavity is disposed between the second portion and the third portion of the cavity;

wherein the cutting member is removably disposable in the first portion of the cavity between the first urging member portion and the second urging member portion;

wherein the first urging member portion and the second urging member portion are portions of a leaf spring; and

wherein the leaf spring includes a recess configured to receive a back end portion of the cutting member when the cutting member is disposed in the first portion of the cavity.

2. The cutting device of claim 1 , wherein the leaf spring is an X-shaped leaf spring.

3. The cutting device of claim 1 , wherein the cutting member is reversibly disposable in the first portion of the cavity.

4. The cutting device of claim 1 , wherein the cutting device is a surgical scalpel.

5. The cutting device of claim 1 , wherein a width of the first portion of the cavity is greater than a width of the second portion of the cavity and a width of the third portion of the cavity.

6. The cutting device of claim 1 , wherein an inserted length of the cutting member that is disposed in the cavity is greater than or equal to an exposed length of the cutting member that protrudes from the cavity.

7. A cutting device, comprising:

a body member having a cavity that extends from an opening at a front end portion of the body member toward a back end portion of the body member;

a cutting member partially disposed in a first portion of the cavity; and

a first urging member portion disposed in a second portion of the cavity and a second urging member portion disposed in a third portion of the cavity;

wherein the first portion of the cavity is disposed between the second portion and the third portion of the cavity;

wherein the cutting member is reversibly disposable in the first portion of the cavity between the first urging member portion and the second urging member portion;

wherein the first urging member portion urges against a first surface of the cutting member when the cutting member is disposed in the first portion of the cavity; and

wherein the second urging member portion urges against a second surface of the cutting member, the second surface being disposed at an opposite side of the cutting member from the first surface, when the cutting member is disposed in the first portion of the cavity.

8. The cutting device of claim 7 , wherein a width of the cutting member is greater than a width of the first urging member portion and a width of the second urging member portion.

9. The cutting device of claim 7 , wherein the cutting member is formed from Zirconium Oxide.

10. The cutting device of claim 7 , further comprising a weight disposed at the back end portion.

11. The cutting device of claim 7 , further comprising a cover that is removably attachable to the front end portion and the back end portion.

12. The cutting device of claim 7 , wherein the cutting device is a scalpel.

13. The cutting device of claim 7 , wherein the cutting member is a replaceable blade.

14. A cutting device, comprising:

a body member having a cavity that extends from an opening at a front end portion of the body member toward a back end portion of the body member;

a replaceable blade partially disposed in a first portion of the cavity; and

a spring having a first spring portion disposed in a second portion of the cavity and a second spring portion disposed in a third portion of the cavity;

wherein the first portion of the cavity is disposed between the second portion and the third portion of the cavity;

wherein the replaceable blade is removably disposable in the first portion of the cavity between the first spring portion of the spring and the second spring portion of the spring; and

wherein the spring includes a recess configured to receive a back end portion of the replaceable blade when the replaceable blade is disposed in the first portion of the cavity.

15. The cutting device of claim 14 , wherein a total length of the body member is between about 4 times and about 6 times of a length of the cavity.

16. The cutting device of claim 14 , wherein the spring is a leaf spring and the cutting device is a scalpel.

17. The cutting device of claim 16 , wherein the replaceable blade is reversibly disposable in the first portion of the cavity.

18. The cutting device of claim 7 , wherein each of the first urging member portion and the second urging member portion includes one or more arc-shaped strips of steel.

19. The cutting device of claim 7 , wherein the first urging member portion and the second urging member portion form a two-part leaf spring.

20. The cutting device of claim 7 , wherein each of the first urging member portion and the second urging member portion includes a plurality of strips of metal that are curved and attached together.
