The Gokstad Viking ship. Little known fact: Norse ships began to use iron rivets beginning of 3rd cent AD (before they lashed planks together). Shipbuilders also put a tarred string of wool in the overlap between planks for a water tight seal, then the rivets went into place. Norsemen did not have saws...axes were the primary tool of choice.
