All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of fabricating a blade for a cutting tool, in particular for a knife, a pair of scissors, a saw, a household appliance, or indeed an industrial tool, the blade (1) being made of steel or an alloy of stainless steels and having at least one cutting edge (3; 103) extending over at least a portion of its periphery, the method being characterized in that it comprises the following steps:
a) making a blade body (2; 102) possessing at least one free edge (F; 4) provided in the vicinity of the location of the or each cutting edge (3; 103);
b) projecting a make-up material (M; M\u2032) in the form of a powder (5; 105) onto at least one free edge (F; 4), the hardness of the make-up material being greater than the hardness of the blade body;
c) subjecting the make-up material powder (5; 105) to a laser beam (8) so as to form a bead (6) or strip (109) on at least a portion of said free edge (4; F); and
d) forming the cutting edge (3; 103) in the bead (6) or strip (109) of make-up material (M; M\u2032).
2. A method according to claim 1, characterized in that said free edge is formed by a flat (4) extending perpendicularly to a main plane (P) of the blade body (2).
3. A method according to claim 1, characterized in that said free edge is formed by a portion (F) of the blade body (102) extending in a main plane oriented at a non-zero angle (\u03b1) relative to a main plane (P\u2032) of the blade body (102).
4. A method according to claim 1, characterized in that the blade body (2; 102) presents dimensions that are slightly smaller than those of the final blade (1).
5. A method according to claim 1, characterized in that the cutting edge (3; 103) is made by grinding, machining, or abrading at least the bead (6) or the strip (109) of make-up material (M; M\u2032).
6. A method according to claim 1, characterized in that the blade body (2; 102) is machined or ground at the same time as the cutting edge (3; 103) is being made by machining or grinding.
7. A method according to claim 1, characterized in that the blade body (2) is machined or ground before the step of forming the bead (6) of make-up material.
8. A method according to claim 1, characterized in that prior to step d) of forming the cutting edge, a hardening and tempering operation is performed on the blade body (2; 102) fitted with the bead (6) or strip (109) of make-up material (M; M\u2032).
9. A method according to claim 2, characterized in that said removal of material is performed from an edge (F0) of the blade body (102) opposite, relative to the main plane (P\u2032), from the edge (F) of the blade body (102) on which the make-up material (M\u2032) is deposited.
10. A blade for a cutting tool, in particular a knife, a pair of scissors, a saw, a household appliance, or an industrial machine, the blade having at least one cutting edge on at least a portion of its periphery, and being characterized in that it comprises a blade body (2; 102), the cutting edge (3; 103) being supported on one edge of said blade body (2; 102).
11. A blade according to claim 10, characterized in that the cutting edge (3; 103) and the blade body (2; 102) are made of at least two different materials.
12. A cutting tool, in particular a knife, a pair of scissors, a saw, a household appliance, or indeed an industrial machine, characterized in that it includes at least one blade made according to claim 10.
