Claim:
A method of fabricating a blade for at least one of a knife, a pair of scissors, a saw, or a household appliance, the blade being made of steel or an alloy of stainless steels and having at least one cutting edge extending over at least a portion of its periphery thereof, the method comprising the following steps: a) making a blade body possessing at least three free edges provided in a vicinity of the at least one cutting edge; b) projecting a make-up material in the form of a powder onto one of the at least three free edges wherein said one of the at least three free edges is formed by a flat horizontal surface extending perpendicularly to a main plane of the blade body, the hardness of the make-up material being greater than the hardness of the blade body wherein said powder contains at least two elements connected together; c) subjecting the make-up material powder to a laser beam at the same time as projecting the make-up material powder so as to form a bead or strip on at least a portion of one of the at least three free edges so that the bead or strip melt instantaneously with blade body to form an intimate bond with the blade body; d) after said intimate bond is formed, performing a hardening and tempering operation on the blade body and the bead or strip; wherein said blade body is fitted with the bead or strip of the make-up material; and e) forming the cutting edge in the bead or strip of make-up material so as to form a sharp edge.
