摘要：
Blades of steel with long edge life for chopping devices for cutting up straw and the like, which devices are equipped with blades mounted on rotating drums and with counterblades which fit into the gaps between the blades, the blades being produced by rolling at least one of the longitudinal edges of a piece of steel strip to form a slightly rounded, prismatic cutting edge, the rolling being continued until satisfactory sharpness is obtained.
