In order to keep the cutter from rusting and make the appearance of the cutter smooth and beautiful, a three-layer composite cutter is manufactured by using three-layer metal composite plates of stainless steel, high-carbon steel and stainless steel.

When the three-layer metal composite plate of stainless steel, high-carbon steel and stainless steel is manufactured, the two sides of the high-carbon steel plate are respectively attached with one stainless steel plate, and the three-layer metal composite plate for the cutter is manufactured by a high-temperature rolling composite method.

When the three-layer metal composite plate for the cutter is manufactured, the stainless steel plate compounded with the two sides of the high-carbon steel plate is a stainless steel plate made of a single material. When the stainless steel plate and the high-carbon steel plate which are made of single materials are compounded, no transition layer is arranged between the stainless steel plate and the high-carbon steel plate, the stainless steel plate and the high-carbon steel plate are directly combined, the bonding strength of a compounding interface is not high, and the stainless steel plate is easy to break and delaminate during quenching and quenching. Therefore, when the three-layer metal composite plate for the cutter is manufactured, a stainless steel plate with a transition layer needs to be compounded.
