The equilibrium crystal shape (ECS) for the body-centered solid-on-solid (BCSOS)model in the how-temperature phase is studied. Based on the equivalence between the BCSOS model and the asymmetric six-vertex model, the surface free energy f(ρ) (ρ : step density) is calculated for general mean surface tilt angle. In the expansion, f(ρ)=f(0)+αρ+βρ^3+O(ρ^4), the universal relation between a and b is verified. Accordingly, the Gaussian curvature of the ECS is shown to assume a universal finite jump at any position of the facet edge of the crystal.
