A grenade grip is a lightsaber hilt grip section style characterized by a series of intersecting grooves. The grooves, which vary in depth, are sometimes ‘pineapple’ like in texture and appearance.
The Obi-Wan Kenobi’s lightsaber in Star Wars Episode IV: A New Hope (1977) is the first lightsaber to use the grenade grip style. The Star Wars prop department constructed the upper grip section of Kenobi’s lightsaber using a World War I era British No.3 Mk1 Rifle Grenade (hence the term ‘grenade grip’).
Although lightsaber enthusiasts commonly associate a deep-grooved grenade grip specifically with the Obi-Wan Kenobi lightsaber, custom lightsaber companies occasionally incorporate grenade style grips into other lightsaber hilt designs as well.
Some notable custom sabers using a grenade grip include:
Eris, Maurauder, Venom, Venous Fury, Viper
Arbiter, Aeon V5, Dominix V5, Initiate V5
