A cutting device is disclosed. The cutting device has a body member formed from a first material and including a cavity extending along a length of the body member from a first end of the body member to a second end of the body member that is disposed on an opposite side of the body member as the first end, a cutting assembly formed from a second material and attached to the body member, the cutting assembly including a protrusion, and a cutting member disposed on the cutting assembly. The body member includes an aperture extending from the cavity to a third end of the body member that is disposed between the first and second ends. The cutting assembly is attached to the body member based on the protrusion being received in the aperture. The first material is more flexible than the second material.

What is claimed is: 1. A cutting device, comprising: a body member formed from a first material and including a cavity extending along a length of the body member from a first end of the body member to a second end of the body member that is disposed on an opposite side of the body member as the first end; a cutting assembly formed from a second material and attached to the body member, the cutting assembly including a protrusion; and a cutting member disposed on the cutting assembly; wherein the body member includes an aperture extending from the cavity to a third end of the body member that is disposed between the first and second ends; wherein the cutting assembly is attached to the body member based on the protrusion being received in the aperture; wherein the first material is more flexible than the second material; and wherein the cutting assembly includes a holder member having an aperture that receives the cutting member, and a cover member that is attached to the holder member over the cutting member. 2. The cutting device of claim 1 , wherein the second material has a higher hardness on a durometer scale than the first material. 3. The cutting device of claim 1 , wherein the first material has a durometer scale value that is “soft” or “medium soft” on a Shore Hardness Scale. 4. The cutting device of claim 1 , wherein the second material has a durometer scale value that is “hard” or “extra hard” on a Shore Hardness Scale. 5. The cutting device of claim 1 , wherein the first material is silicone rubber. 6. The cutting device of claim 1 , wherein the protrusion is a flange that protrudes from an adjacent portion of the cutting assembly by a protruding distance that is between 1 and 2 millimeters. 7. The cutting device of claim 6 , wherein the cutting assembly is attached to the body member based on the flange formed from the second material being received in the aperture that includes an aperture protrusion formed from the first material and having a width that is equal to the protruding distance. 8. The cutting device of claim 1 , wherein the body member is ring-shaped and the cavity is a user finger through-hole. 9. The cutting device of claim 1 , wherein an interior wall of the body member forming the cavity tapers inward from the first end that is a rear end of the body member to the second end that is a front end of the body member. 10. The cutting device of claim 9 , wherein the body member includes a wall portion, which includes the interior wall, and a base portion that increases in height from the rear end to the front end of the body member. 11. The cutting device of claim 1 , wherein the cover member is ultra-sonic welded to the holder member over the cutting member. 12. The cutting device of claim 1 , wherein the cutting member is a ceramic blade that is disposed at an angle relative to the length of the body member. 13. A cutting device, comprising: a body member formed from a first material and including a cavity extending along a length of the body member from a first end of the body member to a second end of the body member that is disposed on an opposite side of the body member as the first end; a cutting assembly formed from a second material and attached to the body member, the cutting assembly including a protrusion; and a cutting member disposed on the cutting assembly; wherein the body member includes an aperture extending from the cavity to a third end of the body member that is disposed between the first and second ends; wherein the cutting assembly is attached to the body member based on the protrusion being received in the aperture; wherein the second material has a greater stiffness than the first material; and wherein the cutting assembly is attached to the body member based on the protrusion formed from the second material being received in the aperture that includes an aperture protrusion formed from the first material. 14. The cutting device of claim 13 , wherein the second material has a higher modulus of elasticity than the first material. 15. The cutting device of claim 13 , wherein the first material has a Shore A Hardness value of between about 20 A and about 45 A. 16. The cutting device of claim 13 , wherein the second material has a Shore D Hardness value of between about 70 D and about 95 D. 17. The cutting device of claim 13 , wherein the body member is ring-shaped and the cavity is a user finger through-hole. 18. A cutting device, comprising: a ring-shaped body member formed from a first material and including a through-hole extending along a length of the ring-shaped body member from a first end of the ring-shaped body member to a second end of the ring-shaped body member that is disposed on an opposite side of the ring-shaped body member as the first end; a cutting assembly formed from a second material and attached to the ring-shaped body member, the cutting assembly including a flange; and a ceramic blade disposed on the cutting assembly; wherein the ring-shaped body member includes an aperture extending from the through-hole to a third end of the ring-shaped body member that is disposed between the first and second ends; wherein the cutting assembly is attached to the ring-shaped body member based on the flange being received in the aperture; wherein the first material is silicone rubber and the second material is stiffer than silicone rubber; and wherein the cutting assembly is attached to the ring-shaped body member based on the flange formed from the second material being received in the aperture that includes an aperture protrusion formed from silicone rubber. 19. The cutting device of claim 18 , wherein the flange protrudes from an adjacent portion of the cutting assembly by a protruding distance that is 1.5 millimeters. 20. The cutting device of claim 19 , wherein the aperture protrusion has a width that is equal to the protruding distance.
