The head of this grenade is a thin steel casing containing the explosive filler. This is screwed onto a hollow wooden handle through the center of which runs a double length of cord. This cord connects at the forward end to a friction pull igniter (B. Z. 24) and at the rear to a porcelain ball in a metal cap. In operation, the cap is removed, the porcelain ball pulled, and the missile thrown to detonate after a 4-5 second delay.
