Model 17 grenade
The Model 17 Eierhandgranate is a small defensive and offensive hand grenade which was used by Germany during World War I.
Design
The Model 17 was more portable than the heavier Kugelhandgranate and less awkward to handle than the stick grenade.The body of the Model 17 was initially smooth and thus difficult to hold so the design was modified with the addition of a raised band for better grip.
A similar grenade called the Model 39 grenade was later introduced by Germany and used in World War II.
The average soldier could throw a Model 17 40 meters or further.
