The alternate slang name for the World War I era grenade that the egg grenade was less awkward than to handle was the potato masher.
 It was more portable than the heavier Kugelhandgranate and less awkward to handle than the Stick grenade. 
 The very distinctive appearance led to it being called a "stick grenade", or "potato masher" in British Army slang, and is today one of the most easily recognized infantry weapons of the 20th century.
