The invention relates to the field of manufacturing technologies of mechanical cutters, scissors and moulds, in particular to a manufacture method of stock of high alloy tool steel mechanical cutters, scissors and moulds and the stock. High alloy tool steel is used as a consumable electrode which is in fusion splicing with precast body base metal through electroslag and cast into a groove. Cutterstock, scissor stock, mould stocks, and the like are manufactured by the same way. Electroslag remelting adopted by the method is a melting method which can be used for obtaining pour metal by a resistance heat source generated by slag and can improve the purity, achieve low sulphur content and reduce non-metallic inclusion, and a metal structure welted by the melting method is clean, uniform andcompact. The method not only can ensure that cutting edge material has better quality than a cast ingot (consumable electrode), but also is welted and compounded with the body base metal, thereby being a two-in-one process (i.e. a one-step method which is beneficial to simplifying the production process). Due to achieving the metallurgical bonding effect, the composite stock is suitable for beingmade into various cutters, scissors and mould products used under various working conditions.
