Document Type and Number:
WIPO Patent Application WO2005089995
Kind Code:
A8
Abstract:
The invention relates to a method of producing a blade (1) for a cutting tool, such as a knife, a pair of scissors, a saw, a household appliance, an electrical appliance or even an industrial machine. According to the invention, the blade (1), which is made from steel or a stainless steel alloy, comprises at least one cutting edge which extends along at least part of the periphery thereof. The inventive method is characterised in that it comprises the following steps consisting in: a) producing a blade body (2) having at least one free edge close to the position of each cutting edge (3); b) spraying a powder filler material with a greater hardness than that of the blade body onto at least one free edge; c) subjecting the powder filler material to a laser beam such as to form a bead or strip along at least part of the free edge; and d) forming the cutting edge in the bead or strip of filler material. In this way, the cutting edge of cutting tools equipped with one such blade have high wear resistance.
