Cue the Holy Hand Grenade jokes

A RELIC: Crusader-era grenade dug out of central Israel home. Family shows metal artifacts retrieved from sea by late father, including knife-head some 3,500 years old (Sue Surkes, Times of Israel).

The early grenade would have been filled with Greek fire, sealed and hurled at an enemy, a weapon common in Israel from the 11th to 14th centuries CE.

It was used during the Crusader, Ayyubid and Mamluk periods, according to the IAA.
