We construct explicit solutions of the anisotropic motion of closed polygonal plane curves by a power of crystalline cuvature, in the case where the initial curves are nonconvex and the power is less than one: The solutions develop degenerate pinching singularities of a "whisker"-type and a split-type in finite time, and do not become convex polygons. Moreover, in the splitting case, we conjecture degenerate pinching rate from numerical experiments.
