The tool has a strip-shaped base body (1) comprising a linear creasing line (2) raised in a region (4) to a front side (3) of the base body, where the region is attached at the front side of the base body. The creasing line has reduced thickness with respect to the base body, and is round in cross-section. The creasing line is chamfered in the region to the front side of the base body, where chamfers of the creasing line enclose an angle in a range of 10 degrees and 15 degrees with linear regions of the creasing line. An independent claim is also included for a flat material comprising grooves. |
