This sexton is used for navingating on ships as they travel around on the ocean. My Dad’s dad gave it to him. I think he sailed on ships.
My great-grandad found these old Maori tools on a river bank. The top left one is an anchor for a canoe. The top right one is a really thin edged cutting tool. The bottom left one a like little carving tool and the bottom right one is a little ink well for storing the ink when making a tattoo or moko. They are very old and precious.
