The King piece with the komashi's name is truly a one-of-a-kind shogi piece.

It is thought that Haretsuki himself carved his own name for his own use and kept it for viewing. (It is a shogi piece with no other examples.) Yuichi's name on the King piece further deepens the special meaning of this wonderful piece. The Mikurajima Tsuge Tokujo-bori of this piece is considered to be the highest-grade material for shogi pieces.
