Here, we call this an `isometric duality'. When the singular set image has no symmetries and does not lie in a plane, the dual cuspidal edge is not congruent to the original one. In this paper, we show that this duality extends to generalized cuspidal edges in $\\boldsymbol R^3$, including cuspidal cross caps, and $5/2$-cuspidal edges.
