oyster, (kokuji)
硴 is a Japanese-made kokuji that combines stone and flower to represent an oyster, likely evoking the hard, stony shell and the flower-like shape of the meat or shell interior.
硴 is a kokuji created in Japan by combining 石 (stone) and 花 (flower) to represent an oyster. The exact historical origin is uncertain, but the components likely reflect the oyster's hard shell and its flower-like appearance.
Picture a stone 石 that opens like a flower 花 to reveal a pearl inside: that stony flower is an oyster.
For かき, imagine a kaki (persimmon) tree growing beside a rocky shore where oysters cling to the stones: kaki -> かき, and the oyster's shell is as hard as the stone.
