When a KCl single crystal is grown by rapid cooling of the melt, the crystal cleaves naturally into fragments. In the natural or artifical cleavage of the crystal various step lines appear on the cleaved surfaces. In the present paper we observed that the shape of a line is straight along the 100-axis and a wavy confusion or zigzag along the 110-axis. Such a confusion of the shape may be described by introducing two confusion factors: G a visual one (G=0 for a straight line) and b defined from the orientation (b=0 along the 100-axis). On the other hand, a sinusoidal approximation of the line gives the wavelength λ. Then we have G_??_b and λ is a function of b. The confusion of the shape of the lines is also related to the macroscopic defects.
