Abstract
A saw blade has at least one carrier part that has at least one cutting side. The saw blade further has a multiplicity of inserts arranged so as to be spaced apart from one another. The inserts are made from a material, in particular a carbide, which is harder than a material of the carrier part. The inserts are each fastened to the at least one cutting side of the carrier part. The inserts each at least partially form at least two saw teeth.

A saw blade, comprising:
- at least one carrier part that has at least one cutting side;
- and
- a multiplicity of inserts arranged so as to be spaced apart from one another,
- wherein the inserts are made from a material which is harder than a material of the carrier part,
- wherein the inserts are each fastened to the at least one cutting side of the carrier part by both a material connection and a positive-locking connection,
- wherein the inserts each at least partially form at least two saw teeth, and
- wherein each of the at least two saw teeth includes a flank surface and a tooth bottom, and the carrier part and/or a brazing or weld melt forms at least a portion of the tooth bottom and/or the flank surface of one of the at least two saw teeth.

A method for producing a saw blade, comprising:
- arranging a plurality of insert blanks so as to be mutually spaced on at least one cutting side of at least one carrier part blank, wherein the insert blanks are made of a material which has a greater hardness than a material of the carrier part blank;
- fastening the plurality of insert blanks to the at least one carrier part blank;
- and
- forming at least two saw teeth, at least partially, on each of the insert blanks such that each of the at least two saw teeth includes a flank surface and a tooth bottom, and the carrier part blank and/or a brazing or weld melt forms at least a portion of the tooth bottom and/or the flank surface of one of the at least two saw teeth.
