Abstract
The invention relates to a process for manufacturing a cutting tool for a vegetation cutting machine, such as a brush cutter or an edge trimmer, comprising the following steps: (a) producing by an injection molding process at a first temperature a preform (200) made of a polyamide mixture comprising at least one homopolymer and at least one copolymer; (b) stamping the preform at a second temperature lower than the first temperature so as to cause polymer chains of the polyamide mixture to extend according to at least two different directions, thereby forming a planar piece (201), (c) cutting the planar piece (201) to define at least one cutting edge of the cutting tool (2).

A process for manufacturing a cutting tool for a vegetation cutting machine, comprising:
- (a) producing by an injection molding process at a first temperature a preform made of a polyamide mixture comprising at least one homopolymer and at least one copolymer;
- (b) stamping the preform at a second temperature lower than the first temperature to cause polymer chains of the polyamide mixture to extend according to at least two different directions, thereby forming a planar piece,
- (c) cutting the planar piece to define at least one cutting edge of the cutting tool.
A cutting tool for a vegetation cutting machine, made of a polyamide mixture comprising at least one homopolymer and at least one copolymer, wherein said cutting tool has polymer chains extending along at least two different orientations, and wherein said cutting tool has a substantially planar shape comprising a cutting edge and at least one attachment portion adapted to be attached to a cutting head of the vegetation cutting machine.
