“Crack Thunder” features a blade design characterized by lightning‑like crack patterns, imbuing the weapon with the mystical power of thunder; “Fang Blade” mirrors its curved, razor‑sharp edge reminiscent of a beast’s fangs, emphasizing the weapon’s ferocity and primal nature. Together, these designs perfectly complement dark fantasy or barbaric tribal prop concepts, evoking the imagery of “the fangs of a ferocious beast that summons lightning.”
