Eket

The Eket was a short stabbing sword used by the Númenóreans in war.

The sword was broad bladed and double-edged and was about a foot to one and half feet long in length.

After escaping the Disaster of the Gladden Fields, Isildur, standing at the banks of the river Anduin cast off all of his armour and fighting gear but retained an Eket for self-defense before going into the water.
