   4 of the drawing shows the front view of the eccentric chisel, FIG. 5 shows a thread center longitudinal section through the same, FIG. G shows a bottom view, and FIGS. 7-11 show several cross-sections guided through the chisel blade at different heights.



   As can be seen, on the Schmiilcron chisel side, beginning immediately at point I (Fig. 4), where the other half becomes wider than this, corresponding reinforcements v are made in the material, whereby a weight compensation of both chisels
