Abstract
A chisel includes a working section, a shaft section, and a striking surface. A longitudinal axis runs through the working section, the shaft section, and the striking surface. In a cross section of the working section running transversely to the longitudinal axis, a first structural core region has a first core hardness which is substantially less than a first external hardness in a first external region outside of the first structural core region within the cross section of the working section.
