    • A cutting device with at least one cutting part each comprising a first (1) and a second (2) face meeting at an edge, wherein on at least one of the cutting parts at least a part of the first face (1) immediately adjacent to the edge is harder than the second face (2). A method for manufacturing the cutting device of the invention from at least one prefabricated cutting part of a certain hardness each comprising a first (1) and a second (2) face meeting at an edge, whereby on at least one of the cutting parts at least a part of the first face (1) immediately adjacent to the edge is provided with a layer substantially harder than the material of the prefabricated cutting part.
    • 一种具有至少一个切割部分的切割装置,每个切割部分包括在边缘处会聚的第一(1)和第二(2)面,其中在至少一个切割部分上,第一面(1)的至少一部分紧邻 到边缘比第二面(2)更硬。 本发明的切割装置的制造方法,其特征在于,至少具有一定硬度的预制切割部分,每一切割部分包括在边缘处会聚的第一(1)和第二(2)面,从而在至少一个所述切割部分 与边缘紧邻的第一面(1)的至少一部分设置有比预制切割部件的材料大得多的层。
