The binding agent is light gray, sometimes silvery appearing and widens from the center of the trailing edge and leading edge. It is also sold to the outer dark brown box sharp and extends to the shaft line. This white line is basalwärts bent concave on the front edge. In this concave area the line is relatively broad, only very narrow in the course; First, it follows an acute bulge to the side, then a wide and shallow bulge and the trailing edge has a rounded, wide and shallow bulge.
