37 3/8” length. Opened seam conical socket and cylindrical shaft. Medially ridged, paddle shaped iron head with forged on hardened edge, evident in the contrasting rust patterns. Stable brown surface rust. Used to dispatch the whale after it has been exhausted by pulling the dory in the Nantucket Sleigh Ride. The dying whale spouts red and the crew shouts “Chimney’s afire!” Killing lances were not identified to the ship as they were not prone to loss in a whale as were harpoons.
