Sharp-edged cutting tools

1. A cutting tool comprising:

a blade portion having a sharpened edge and a body portion;

wherein at least one of the blade portion and the body portion are formed from a bulk amorphous alloy material, and where at least one portion of the bulk amorphous alloy material has a thickness of at least 0.5 mm.

2. The cutting tool as described in claim 1 , wherein the bulk amorphous alloy is described by the following molecular formula:

(Zr,Ti) a (Ni,Cu) b (Be) c , wherein “a” is in the range of from about 40 to 75, “b” is in the range of from about 5 to 50, and “c” in the range of from about 5 to 50 in atomic percentages.

3. The cutting tool as described in claim 1 , wherein the bulk amorphous alloy is described by the following molecular formula:

Zr 41 Ti 14 Ni 10 Cu 12.5 Be 22.5 .

4. The cutting tool as described in claim 1 , wherein the bulk amorphous alloy has an elastic limit of at least about 1.2%.

5. The cutting tool as described in claim 1 , wherein the bulk amorphous alloy is based on iron, cobalt, and/or nickel wherein the elastic limit of the bulk amorphous alloy is about 1.2% and higher.

6. The cutting tool as described in claim 1 , wherein the bulk amorphous alloy is described by a molecular formula selected from the group consisting of: Fe 72 Al 5 Ga 2 P 11 C 6 B 4 and Fe 72 Al 7 Zr 10 Mo 5 W 2 B 15 .

7. The cutting tool as described in claim 1 , wherein the at least one portion formed from the bulk amorphous alloy has an elastic limit of at least about 2.0%.

8. The cutting tool as described in claim 1 , wherein the bulk amorphous alloy further comprises a ductile metallic crystalline phase precipitate.

9. The cutting tool as described in claim 1 , further comprising a handle mounted onto the body portion.

10. The cutting tool as described in claim 9 , wherein the handle is formed from a material selected from the group consisting of: a plastic, a metal and wood.

11. The cutting tool as described in claim 1 , wherein at least the blade portion is formed from the bulk amorphous alloy.

12. The cutting tool as described in claim 1 , wherein the sharpened edge is formed from a bulk amorphous alloy and has a radius of curvature of about 150 Angstroms or less.

13. The cutting tool as described in claim 1 , wherein the blade portion is further coated with a high-hardened material selected from the group consisting of: TiN, SiC and diamond.

14. The cutting tool as described in claim 1 , wherein the cutting tool is anodized.

15. The cutting tool as described in claim 1 , wherein the cutting tool is in the form of one of either a knife or a scalpel.

16. The cutting tool as described in claim 1 , wherein the sharpened edge is serrated.
